Rear seats in a club cab, Help?!?!

[KBalzuweit]

I just won a set of seats out of a 99 quad cab on ebay, it included the rear seat also. Has any one put one in a first gen. I have seen seats back there but they all looked like Chevy/GMC seats. They should be here by Monday, can not wait to sit in comfort!!







Thanks, Karl

Here is a pic of the rear seat. Not bad for $233. 50 for both seats

I'm putting in a set of seats as well that I also got from ebay - I think they come in this Friday. We'll have to keep each other posted on the status. Still needing a second set for the back half of my crew cab tho... have to keep looking.

You must be samsprojects on ebay, I thought at $233 I got a deal, but $200 for power... WOW. How bad did they hit you for shipping? Sorry about beating you out at the last second.

Hi Karl - no worries at all bud. Proxy bidding is tricky at best - I was more bummed the other guys were bidding way early and jacking up the price. The color codes were exactly the same which is what made the two sets such a good deal for my 4-door rig. 'Sokay, there'll be more. I got pretty lucky on the set I found, so I have decent fronts now. I haven't got them yet but they're coming in on a pallet - cost $150 to ship -still a great deal at $350, just hope they work. I figure the seat belt buzzer thingie will work either way for the wiring - just have to make the new set 'talk' to the old harness... same as it ever was.

If I get them tomorrow or Friday I'm probably going to install them this weekend, or at least figure out the bracketry, etc. I'll try to get some good pics of the brackets if I end up making any and post 'em. Either way, these are going to be much better than the ole bencher in there now! - Should make the trip up to Piers next month a lot nicer.

Are you going up for their dyno day? It is tentatively set for 19 July, but that's not firm. They just got a new dyno and I think I'm going to make the 1100 mile trip up and make a nice week of it. Never been up that way... and we're planning to kill a KDP or two in the process. Always something...

If those 99 seatsbelts use the Seatbelt Control Module (SCTM) you have to hook all that up. Its a black box under the middle seat. You'll also need the harness that plugs into the box. I hope they sent that. The retractors in the seats use solenoids to control alot of the safety features of the retractors. They are partially responsible for seatbelt lockup during high angle lean and G-force loading. If you choose to just leave it unplugged the solenoids default with no power is locked up... so you'll have to hook it up. It is also connected to the 99 airbag control module for fault sensing in the SCTM. You shouldn't need to worry about that as your truck does not have airbags or the AIRBAG warning light on the dash cluster. I can PM you with some helpful hints from the 99 service manual on what to do or not do.



Otherwise you wont be able to use them and that would not be too safe. Some time in 00 or 01 they got rid of the SCTM and went with fully mechanical retractors.



The problem with the older 99 seats were that if you lean back the retractors also go back... which wont allow the pendulum to work so the solenoids assist them.

3rd Gen Seats

Gents, I am also installing a set power seats in my 1st '93 Crew Cab. Still trying to figure out the seat wiring though. Mine was an Ebay purchase. Got both front and back, tan leather. Total price was $201 (I went and picked them up). Bought them from a salvage yard in Topeka KS. Had a good experience with them. I too will shoot pictures as the install progresses. I have no idea how I will install the back seats. But I am looking forward to having them in. My bench is a little solid.

 

[EMedlin]

Ncostello, If you don't mind I would like the tips as well. I have the little box and most of the wiring harness. Thanks.

 

[Ncostello]

No problem... let me review the service manual wiring diagram to get my wiring colors right. I cant remember off the top of my head which colors do what. I've heard of some just using the stock seatbelts on the b-post and not using the in-seat belts at all. But I wouldn't like that.

 

["Mad Max"]

New seats = good, old seats = ...old

Neither would I - I want to use the belts integral to the seats, in fact I got those seats specifically because my crew cab doesn't have the provisions for shoulder harnesses in the middle pillar, and the rear ones don't have any either.

So I'll definitely be fighting the wiring battle, but it'll be worth it in the end. Many of my friends own 2nd gen trucks and every time I ride in them I want to steal the seats.

 

[KBalzuweit]

If anybody gets the wiring correct please post it or email me. I too want to do my install correct. Also any idea on what to do about shoulder belts for the rear seat?? The whole reason for my project is to make it a little safer and comfortable for the kids in the back. THANKS FOR ALL YOUR HELP!! THIS SITE ROCKS!!

You folks dont even want to know what I know about SCTM's. It would take you hours to read so I'll just tell you how I would wire it up to make it work.



The harness should have wires of these colors and this is where they go or what they hook to. Note: not all of the pins of the SCTM pin cavity do a job. Some are blank and serve no purpose on Dodge truck seats. Also the drivers side will have an extra wire coming down from the retractor. Its the idiot light sensor to remind you to put the belts on. You shouldn't have to hook it up to make this work. Its for the airbag module equipped trucks with the appropriate dash light warning system.



BK/PK wire is the SCTM ground

BL is a 12V power feed

PK is a 12V power feed

BK/LG is a ground wire for the solenoids ground side wire (also BK/LG).



OR/BK is for the left retractor solenoid.

OR/RD is for the right retractor solenoid.



LG/BK goes to the airbag module as a fault code low voltage indicator. It normally supplies the ABCM with 3V to let the airbag system know the SCTM is OK. You wont have airbags so forget this wire.



TN is the left door switch

TN/RD is the right door switch

Both of these dont have to be used if... .



you hook both the pink and blue wires to the same key-on 12V power source. These two wires need 12V. The pink is supposed to have constant 12V power while the blue gets key-on only 12V power. If they are both hooked to a key on source, the seatbelts can only be retracted and put on whey you start the truck (which is how I do it). Taking the belts off doesn't matter... you can still do this whether the ign is on or off. The SCTM has a timer function that shuts off a constant 12V source after 30 minutes and the door jamb swiches bring the unit back to life when you open the door. So as not to confuse... again the pink and blue wires can be wired to a single 12V power source that comes on when you turn the ignition key on.



If you get in wreck and the battery is crushed and destroyed... the belt will remain locked up as the default mode is lock up. You can still take them off, you just cant pull them out further at that point.



That will get you going. I dont want to go into the entire logic of the SCTM as its a very long process and I'm tired of typing already. It is important to have the harness so you have the proper color wires to work with. If you dont I can email you a PDF file of the pinout diagram of the module so you will know which pins do what on the SCTM box. But I'll have to email that as the attachments here dont support PDF.



These colors are from a 99 manual. I think 98 seats are the same and perhaps the 2000 seats if they still used SCTM's then.

 

[Ncostello]

I should also say that the door jamb switch sensors, 30 minute timer feature, etc are convenience features that play into effect on the 2nd gen trucks.



What I have written is basically going to get your seatbelts working in what I feel is a safe method. There really isn't an unsafe way to wire them up. Either the solenoids are supplied power by the SCTM or they dont. If they dont your belts wont pull out and you cant use them.



I should also ask you to tug the belts real hard and fast (simulate a collision) when your all hooked up and running. There is still a mechanical mechanism lockup on the retractors (there is on mine anyway). I'm assuming the Dodge design was for the solenoids to assist this mechanism in lockup duties. They really went out of their way to make it as stupid as possible... which is why on the late model QC's they trashed the whole setup and went with totally mechanical retractor that still works if the seat back are leaned way back.



The SCTM will however lock up the belts irregardless of this mechanical retractor deal if there is high g-forces or the whole truck is tilted more than 45 degrees in any direction. There is a balance sensor in the SCTM. You can hear it rattle if you shake the black box.

Great idea!



Duh! What was the search critia used? Have cloth buckets and console and looking to switch to the 60/40 and rear bench.

 

[KBalzuweit]

No seats yet, they said Monday or Tuesday. Hey Samsrams, did your show up?? Thanks to Ncostello for the email with diagram!!

 

["Mad Max"]

Negative seats

Nope - didn't show up -I'm thinking next week as well. And I'd also like to thank to NCostello for the wiring intel! Sounds involved but doable.

Hooking one up isn't hard at all. Trying to troubleshoot one in a 99 because its killing your batteries is tough. I ordered my 99 Chrysler Service Manual just for this task. Those little boxes do one thing... they lock and unlock two solenoids... but at very specific times depending on many various "data" inputs.



The timer feature and door jamb switch wires only make it convenient. Chrysler didn't want to sell a truck that had to have the ignition on before you could put the belts on. I personally have no problem with this as I let the truck warm up for a minute anyway and theres not much to do. Some folks may want to buckle up before they start up. Keep in mind... you can still wire them up as intended with two separate power feeds (one constant, the other key on) and the door jamb switch control wires. That way they will unlock when you open the door and the solenoids will shut down (quit drawing 0. 5 amps) after 30 minutes of the ign being shut off.



Glad to be of any help.

Trucking company just called and I am off to pick my seats at the terminal. Can not wait to sit in comfort!!

I got my seats!!

They are here!! Came on a pallet and were shrink wrapped. They look good and feel good (of course I sat on them). I am planning on installing the fronts tomm. The rear looks to be a project so it will have to wait a week or so. I still need to get some seatbelts for the rear. I will post a pic when done.

 

["Mad Max"]

New seats = Really-way-darned-nice!

Mine also showed up - yesterday - wrapped in LOTS of black plastic..... and... . the little electrical boxes that are supposed to be under the console... . are THERE! So, it's off to the fab shop to break out the steel, MIG, beer, drill press, sawzall, wiring diagrams (ala TDR), paint, apolstery cleaner... ... . 10 hours and a few cold ones later, followed by my latest issue of TDR and a good nights sleep!

Probably be later next week before I get the time to do the whole swap, and I'll try to post some good pics with measurements, etc, and maybe a final diagram of the wiring and how it all worked out. Should be a fun, yet involved, project - and well worth it.
