air dog II.. now tbc fault n no cruse

so i end paying a guy to put on my air dog II since he does alot of fass systems

well i get my truck back and i have a tbc fault on the dash and it comes up nearly every time i hit the breaks

my cruse dont work.. im not able to turn the cruse on

and!! i have a small diesel leak.. i can fix that though

so i was wondering what i could look for to solve this problem.. could it be the guy did a bad wiring job or my cruse just happen to go out and i have trouble with my trailer break controller all of a sudden at the same time??

and my fuel pressure changes between about 5psi.. i will start my truck and itll run between 50-52psi.. then the next time ill start it up it will be 56-58psi.. it goes back and forth from each start.. is that normal??

the only way to find out is to trace all the wiring that was done and the wires to the things your having issues with, personally sounds like a bad install with the fuel leak and wiring issues jmo. hope you can figure all these things out

i found out where the problem is but do not know how to fix it.. i looked around for fuse information and found that fuse 12 in the fuse box under the hood would lead to no cruse, tbc fault with chime and that is exactly what i have.. when i checked the fuse box.. sure enough he has a wire tied in to that fuse.. anyone have any suggestions on what i could do??

Go to AirDog's web site and download the install manual. Sounds like that wire was landed in the wrong place or the piggy back fuse is not right. Either way the wiring instructions are pretty good, I had a more difficult figuring out the fuel routing system. They could use soem help with those instructions.

Looks like you need to find another guy to work on your truck.
By the way, keep a very close eye on that fuel pressure. If it falls to 45psi, it will wipe out your injectors. 45psi is the absolute bottom for fuel pressure.

I am assuming thats a remote on wire to trigger the relay but a manual should tell you what its for but I think its feeding off the wrong fuse

You would think that if it is relay driven, a "direct to battery" connection would be ok, as long as there was a fuse inline somewhere. The trigger wire would kick it on and off....right?
