Does anyone have a diagram for the single wire door locks on the 2003 ram.

I'm working on the same vehicle. It's apparently 819 ohms for lock and 320 ohms for unlock through a single wire.... you can find it in the driver's kick, it's white with a green stripe..... i haven't had success with it as of yet, but i do know that wire is the one because it tests with ground and locks the doors posted_image

I hate these new brainstorms that Chrysler comes up with... if you happen to run accross the tach wire, email me directly... maximumboom2000@yahoo.ca ..... thanks

I have done a few of those and the thing that I had a hard time getting used to was remembering that even though they operate with a neg. pulse you still have to run relays to amplify the ground, and then run the pulse through your resistors. Just a thought!! I hope it helps.
