I was wondering if fusing the tail, rt, and Lt circuits would elimate any chance of the front control module seeing a ground and taking it out. My thought was to make a short plug and receptacle with a 3 fuse box in it. I tow different trailer and want to protect that module. O3 ram 3500 Thanks Tim
 
Oh, if this already has fuses, why are folks losing the front control module when towing? Probably worrying for no reason. thanks, tim
 
Its a 20amp, I have been running 10amp with My trailer(s) for close to 1 Year same fuse, although some trailer(s) with heavy lighting will blow the 10amp.
 
Wait, the Factory fuse is 15amp ,put 10amp in place of the 15amp and Yes it's 47,I don't know why it's always the R-Turn circuit that burns out and the left never seems to be a problem.

. I have replaced 3/4 TIPMs In 03/04 the 10amp has protected the circuit, Trailer wiring in some respects is just downright ugly, when the R-Turn is fused at 20amp it is possible to fry the circuit, When 10amp is used it generally has blown 1st protecting the circuit.



I have seen 20amp fuse in the 47 port in many trucks,BC the trialers they are pulling are wire poorly, thus when the draw is strong it fries the circuit. 15amp IS THE ABSOLUTE MAX or your wallet is going to be $$$$$ empty. 10amp can be used safely.

I just looked at mine... both LTS and RTS were 15A and the tails were 20A fused. I read this and decided that it might be good preventative maintenance to replace them with lower amp rated fuses (7. 5A and 10A, respectively).



I trust my trailers' wiring to an extent... the one I wired from scratch, another I redid the scotch-loc connectors, and the third, well it seems to work (the wiring is hid, and the trailer is almost 20 years old). I have either a small number of lights or I have LEDs, so the load should be low enough.



Thanks for the insight into this, the TIPM issue has always been a concern but I never read anywhere about how to better protect it. My friend has an 04 like mine, except with a Hemi... he lost his TIPM (RTS only) the first time he hooked up to his almost new TT.
 
Well, I think that I will change all 3 trailers to led lites and reduce the fuses like steved suggested. Boy, the 92 has hubs, mechanical fuel pump, no computers to speak of, no need of the steering box stabilizer, but, I had to have 4 doors, oh well! Will order a shop manual from geno's. Tim
 
more questions

it was '05



COOL... so is it STILL a good idea to downsize the trailer signal fuses on an 05 like people are suggesting?



Or are only the 2006 and up folks having problems blowing out the TIPM?



Where are the fuses for the trailer wiring located, in the main fuse box, or in the TIPM?



If the fuses are in the TIPM, where the heck is IT located?



As always, TIA!!!!
 
You know, I think it is next to battery, however, I am ordering a manual. I think the fuse thing is a must. tim

The TIPM is mounted in the fuse box under the hood by the battery.

it sounds to me that the early 3rd gens are killing the TIPM due to oversized fuses.

The '06 and newer aren't fused at all and will kill the TIPM

Steved, got numbers for the fuses which you downsized?? #47 and... ??
 
You know fellas, where is my brain? I posted the cure for the headlite switch cure in 06 and is running great, in the discontinued parts for 1st gen. I will make a abs box with a molded 7-way plug and a 7-way receptacle with the relays inside to sit on the bumper step by the trailer plug. The tipm will send the low amp signal to the relays and the load of all lites will bypass the tipm. Will fuse in the box also. Too simple! Will take some pictures of the build in case it interests anyone. Box will come from Home Depoe with a condulet rubber fitting for cable. Will not leave on truck when not towing. Tim
 
The fuses are plainly marked under the hood... all have "trailer" associated with them.



I almost want to say 46, 47, and 33???



I actually will need to build a relay box for my coworker as has rts has died... it would be a fairly simple build as everything you need is at the rear of the truck...
