I have a 1999 Dodge Ram 5.9 Magnum pick up and I am trying to fit a Panasonic satellite navigation system in it and the instructions tell me I need to connect the green wire to the Speed Pulse Lead coming from the ECU.

Please can any one tell me which wire this is and how to find it.

Many thanks

Ned

 

I think they want a vehicle speed sensor input. tap into the sensor on the top of the rear axle.
or you can check those wire colors at the axle and see if you can find they up by the pcm. Sorry don't have a wiring schematic.

 

on the white pcm connecter its pin B27 18gauge white w/orange stripe VSS output! its on the white pug at the PCM! hope that helps!

 

Sorted, thank you very much I could not have done this without your help.

Next time I have a problem with my truck I know where to come.
