Hello all, back to Viper 5901 wiring and their darn flex relays. Actually all I need is a correct wiring diagram for the F250 start circuit. I have gone through close to 10 different wiring diagrams. All with different colors that don't match the truck. Really stupid that I can't edit them on this site. But anyways the delimma. I believe I have three ignitions. That is a problem because the 5901 only comes equiped to handle 2.

So here is my wiring leading to the ignition switch in the steering wheel.

I have (4) wires that have a constant 12v with car off.

Yellow, another yellow, BLACK/ orange, and GREEN/ violet

acc = dark blue/green

start = green

Ign = RED / black, grey/ yellow, white yellow

any ides? My only thought is that because the WHITE/ yellow ignition is a smaller wire that it may not be immediately needed during the remote start process, like maybe it gives power to systems that aren't used unless driving like cruise, wipers, ect. Anyone have an accurate diagram for a 2003 f250 deisel?

Some wiring charts list three ignitions but its really two ignitions and two accessory wires.

BTW the above wiring chart is from Bulldog website. Support them when you can, they have very nice wiring charts, all free.

Unfortunately that diagram is incorrect. There is only one acc. and 3 ign. I know I verified with a multimeter. But I found that the 5901 has outputs to more relays to control more igns, starts, or acc.

OK cool.......as long as you mimic exactly what the ignition switch does as you cycle it all the way thru crank and back to run you should be good to go...............
