I beleive I read something on here a while back about the red light not working on the jake brake switch was on. SOmething about the written instructions being wrong and that a couple of wires needed to be swapped.

Any info on this subject?

Thanks

 

I can't remember off hand....

If you look at the wiring diagram in the back of the install book, it will tell ya which two wires to connect together.

I have yet to do mine.

 

On mine the red line came on when I engage the Jacobs exhaust brake. I had a bad switch that rattled and the light stopped working. The dealer fixed it under warranty.
