2007 Dodge Ram 3500 diesel Starter

The wiring is the same as the 2006, with the exception that there may not be a 12 volt starter wire in the ignition harness. It only uses the violet/brown wire to activate the starter with resistance. I have done 1 and used a CHDL7-PK2 module. I didn't use the built in 2nd starter circuit. I used outboard relays and resistors for the 2nd starter and accessory wire. Use the negative parking light wire. The positive one doesn't activate the lights when the truck is running.sparky
