Does anyone have a cab wiring harness diagram? I got a new led cargo light and the dang thing wont go off (clear only ) so I need to start tracing wiring to see what's going on... Diagram would be very handy 

 

Thanks!

Check out the articles section.  It should have what you need.

Startee there first, then google... All I was seeing in the articles was engine wiring, is there more somewhere else? 

Look at the 1999 Cummins wiring map.  It has all the diagrams

Amazing, thank you.

 

 

Confused a little....

 

Crap my video didn't post??

Let me try again, @Mopar1973Man I found those straight away very helpful. My video shows my dilemma..

Problem...

 

Cargo lights are a switched ground (pink/black) with a constant +12V (pink)

 

Brake lights are switched +12V (white/tan)... With constant ground (lt green/black)

 

If the LEDs have common ground then you stuck with what you got. 

 

My idea is I'm going to use the factory lighting but switch then all out for LED bulbs. I've been doing the looking at the bulbs and prices.

@Mopar1973Man I was thinking the same thing...
