Question bout Speed control wire and reverse wire

Posted May 13, 2007 · 03:06 UTC#1

I got a 2004 Chevy Trailblazer EXT, hookin up my D3 to it! Got everything together and will play CD's and radio. But I'm not sure where to splice into for the speed wire and the reverse wire. Could somebody help me with this?

Get at me!!!!! :shock:

Well for your reverse wire, got to your reverse lamps in back of the truck. Tap into the wire there.

As far as the VSS.... good luck with that! lol

Speed Sense dk. green/white PCM

Notes: 4.2L: The PCM is attached to the driver side of the engine. VSS is in the blue plug, pin 32.

5.3L: The PCM is near the lower front driver side of the engine. VSS is in the green plug, pin 50.

If the truck has offstar, there's a smaller black plug at the radio. That should also have a dk green.white wire. Guess what that's vss too.

Reverse Light lt. green + fuse box under left rear seat
