Help, installing ISSPRO Turbo Temp Monitor

[DSobotka]

I recently purchased a ISSPRO, Turbo Temp Monitor for my P/U. If anyone has any help as to what wires to use or how to wire it would be of great assistance. A friend is going to help. He has a 01' that he hooked his to. He hasn't touched the 03' yet, and I would like to have the info ready if he needs it. Thank You in advance.

I installed a painless wiring kit with like 6 hot all the time,and 6 hot with ignition. You should have two terminals for the 12 volt and the two terminals for the thermocouple that should be color coded say red/yellow. It is a very easy job and should have come with good directions. A volt meter may come in handy if not to check for proper voltages. Good luck

ISSPRO Turbo Wiring

I also purchased an ISSPRO Turbo Temp Monitor for installation on my new 03. I guess I was a little naive as on my previous truck, a 92 cummins, the wiring was straight forward and fairly easy. However, this job rapidly became a nightmare. I presently have all of the wiring in place, except for hooking into the actual wire to power up the ignition system. This has caused me no small amount of heartburn. I checked with my Dodge dealer and they told me to look for either a dark blue wire or an orange wire coming off of the ignition harness. I found one orange wire, and two dark blue wires. One orange and one dark blue wire appear to be about 14 or possibly 16 guage wires. The other dark blue wire appears to be possibly 10 or 12 guage. So which wire to splice into without making a mess of the entire wiring harness? So now I am in limbo with the panel removed from the dash, with wires running out to the monitor where it is laying on the floor. Why? Because I read elsewhere that an individual had hooked his up and at shutdown it set off his seatbelt alarms and brake warning buzzers so he had to power up a second bus to shut them up. I also see that Baker auto accessories, who make the shut down timers for Geno's garage have a wiring harness that pigtales into the trucks ignition system without the need for splicing. Could this be adapted for use with the ISSPRO? It sure would be great if anyone from ISSPRO or Baker or some where could give some direct and addequate advice that an electrical novice but general handyman could translate. Meaning no diagrams showing relays and switches and other things that only an electrical engineer can translate.

PS

I asked this basic question about one and a half weeks ago; the only serious reply I received was a suggestion that I purchase the service manuels. Now I am $134. 00 lighter in the wallet but it is still doubtfull that I will be able to translate the trucks wiring diagrams, that I am told exist in the second manuel, when they arrive in a few more days. Makes me wonder if the individual making the suggestion makes a living off of printing the manuals.

If you really want to know what wires to splice into you need the manual. And yes, the Dodge shop manuals electrical flow diagrams are not exactly easy to read. Its not always correct either. It seems they change things faster on the truck then they update he schematics. The circuits are surprisingly complicated these days. Make sure you hook things in the right place or you will have all kings of problems that are hard to trouble shoot in the future.



You might want to find someone that is experienced for the electrical stuff, it is worth it.

CRumsey,

I'm the one who suggested you get the service manual. I have absolutely no afiliation with anyone even remotely connected to the sale of the printed manual. I was simply expressing my OPINION that such a wiring job on a brand new $39000 truck with a $5200 engine MIGHT be worth spending $100 or so on a manual so you could actually perform the wiring without having to take random guesses at the right wire, potentially shorting out your entire electrical system and costing you a bloody fortune to repair. I sincerely apologize for costing you $134. I assumed that since you were attempting this installation that you would be familiar with wiring diagrams and their application.



In preparation for ordering my own turbo temp monitor, I have already reviewed the manual. They key is in the diagram for the ignition switch, I believe. I have not yet, however, referenced the manual with the harness that's actually on the truck... waiting to get my monitor before I do that. I agree with Dieselpowerdude that the diagrams are not always 100% correct. I wish they would print them in color... might be easier to read.

reply Rbattelle

I'm sorry if I offended you with my tongue in cheek message above. I did not mean to, it was my simple attempt at humor. The truth is I had already checked into purchasing the manuals and had delayed it for lack of funds. However, your message gave me the added incentive to order them anyway.

But that does not change the fact that I still am not an electrically savy person when it comes to deciphering those diagrams. Therefor I need someone more astute than I am to to help with the afore mentioned problems.

For those others like myself, surely I can not be the only one. who needs this help it would be nice if ISSPRO or Baker or someone could help out with a wireing harness. It would be worth the peace of mind knowing I was not going to damage my truck.

It is sad to see that the gauge manufacturer didnt send directions. I got my gauge from autometer and I believe it had simple directions. Some suppliers even supply step by step pictures with directions.

 

[Prairie Dog]

I suggest you tap into the power wire that goes to your lighter. It's switched with the key and is easy to get to. Remove the trim panel from around the radio by removing the screw at the garbage bag holder and then just pull the entire panel towards you.

Their will be two wires going to the lighter. One is black and the other is red with a tracer. You wan't the red one.

This is a good source of power because it has good current capacity and it's on it's own circuit.

ignition wire tap

Prairie Dog

I appreciate the help but my problem is a little different than what you describe. The Isspro Turbo temp monitor has six connections.

I hope I am right as I am going by memory right now and this won't be in the order they are in on the actual monitor.

First a ground--no problem to find a suitable spot for this.

Second and Third are the connections for the Thermocouple once again straight forward with positive and negative connections, easy to understand and make.

Fourth is an indicator light that is an option to use and hook up. It is not a problem to put in or leave out.

Fifth is a power feed, it can be attached to any source of power that does not shut down when the key is turned off. Again it can be attached to the battery or other source of power. Not a problem as long as its got a breaker installed.

Sixth, this is the wire that is my problem, it is to be attached to the wire that keeps the truck running when the key is turned on. The reason for this is so that when the key is turned off and removed the ISSPRO will keep the wire powered and the truck running until the appropriate turbo shut down temperature is reached and then cut power to the engine shutting it down. I think this is also where the problem with other alarms going off comes up and so the question of powering up a second fuse buss in the truck is necessary so they don't go into alarm. This information came from a second generation truck and I don't know if it pertains to the third generation trucks or not.

Any help with the sixth described wire would be appreciated.

Sorry for the dissertation I don't mean to confuse or offend anyone and hope this explanation is adequate.

Would it be possible to use a fuse tap on the ignition fuse to gain access to the circuit? (I'm assuming there is an ignition only fuse in the panel... haven't looked myself).

CRumsey,



I was looking over the wiring diagrams a little last night, and as I alluded to in my last message, I believe the "key" is in the ignition switch itself (no pun intended). There are 5 positions for that switch: off, acc, something, run, start. I think the computer judges what condition the engine should be in by a 12v signal at one of those positions. So, what we need to do is "fool" the computer into thinking the ignition switch is still in the "run" position. But we need to make sure, first. I will re-examine my wiring diagram when I get home from work, it should indicate what color wire you're looking for. Hopefully, no 12v signal at any switch position indicates "off". We will need to verify 3 items to be sure I'm thinking of it correctly:



1. There is a +12v signal at the "run" wire off the ignition switch when the key is turned to that position.

2. There is a +12v signal coming from the ISSPRO turbo temp monitor when the pyrometer indicates >300 degrees no matter what the position of the key is.

3. There is no signal anywhere when the key is "off".



These can be checked easily with a voltmeter, especially the temp monitor (since you have it sitting on your floor with all but that 1 wire connected). Like I said, I will check my wiring diagrams later today after work and let you know what I come up with.



And don't worry, I wasn't really offended or anything by your comments... I just wanted to make sure you don't think I was trying to "trick" you into the poorhouse!

Turbo Saver hookup

RBattelle:

You have probably already noticed on a different thread the answer to our question of where to hook up the ignition wire for the TTM, MGonske, I believe was the one who has posted the answer. He checked the wiring diagrams and then did some experimenting and found that it is the dark blue 16 Gage wire in the ignition harness that is the correct one to be used.



I just went out to my truck and in about 10 minutes finished the wire hookup and then took a quick drive around the block. It works! However, the seatbelt alarm light goes on and the charm sounds once, then the brake light comes on and the charm sounds once again. But, after that no more chimes only the lights stay on. This does not appear to be a problem to me.



Thanks to every one involved in helping me with this I am truly happy.

No! I missed that thread! I'll go search for it...

 

[dkollar33]

I am getting ready to install my gauges in the cubby hole under the heater/ac controls. I am hoping to use the preexisting wiring for the heated seats. According to the manual orange/red to power the lights on the gauge, red/dark green to supply the ignition power, and dark green black for ground. Taking a meter to check for diagram accuracy for sure.
