Easy 3 wire hookup. First, do it with battery out of truck (easier to reach PCM)
Hot lead source of your choice, switched - red lead
Second, ENGINE GROUND, not under dash. Negative cable on battery is easy - black lead
Last, red wire with black stripe at the PCM (computer module). It's a B*&^% to find, near the center of the connector - violet lead.
It will bounce all over, but what you are looking for is green when you get on it.
Oh yeah, Solder your connections!
