I have a 1998 Ram that I am swapping a Cummins into. I'm working on my wiring and there are three or four larger connectors that are right between the ABS control and the firewall. Anybody know where they go?

Thanks,

pics?

 

This is a pic from my friend's truck. Unfortunately I didn't have time to trace wires on his.

 

Also another question; how do the wires from a 98 for the fuel shutoff solenoid hook to the ones on a 90?

 

if you have a 98 truck, and a 98 12 valve engine harness, you dont need to mess with those wires, just plug the engine harness into the big square plug in the fuse box and thats it, i take it you are putting a 1st gen engine in? if so there will be three wires on the 98 12v harness, one of them will be hot with the key on, just hook that one wire to the pump solinoid on the 1st gen engine

 

Well my friend's is a '97 and his are all hooked to something. Also, at the moment I'm not getting power to the starter from the ignition switch. I tested the circuit and the starter solenoid, relay, and relay circuit are all ok. I traced the black/white wire from the ground terminal on the starter relay and it goes to one of those plugs. Also, there are two wires that go back to the transmission that I believe are for the back-up lights, and I traced those back to one of the plugs.

As for the fuel shutdown solenoid; there are two flat terminals on the injector pump. I'm pretty sure I know which is the solenoid, but there is also one at the bottom of the pump. Any ideas on that one?

Thanks,
Ross

 

the one at the bottom is the "KSB" aka cold start advance, it does ont need to be hooked up, but if it is it gets power from the shut off solinoid through a temp switch in the intake plate, a 97 and 98 have completely different wireing, is yours a manual or auto, and what harness do you have? is it auto or manual harness

 

mine is a manual with a manual harness

 

anything...?

 

what year is your 12v harness out of?
