doug118 Posted May 27, 2014 Report Share Posted May 27, 2014 I have a GM 4 pin plug but the plug only has 2 wires in it. My alternator has 4 pins. Will the VCM work even though my plug only has 2 wires? They are the center 2 wires Quote 2001 Tahoe.

corona_jeff Posted May 27, 2014 Report Share Posted May 27, 2014 Yes, plug your harness into the backside of the vcm harness and follow the directions Quote Link to comment Share on other sites More sharing options...
Kyblack76 Posted May 27, 2014 Report Share Posted May 27, 2014 (edited) Yes the number of pins dont mean much. I have a oval 4 pin. Only use one from OEM.

doug118 Posted May 27, 2014 Author Report Share Posted May 27, 2014 I know it'll plug in properly but I wasn't sure if having 1 less wire would cause any issues Quote 2001 Tahoe.

Kyblack76 Posted May 27, 2014 Report Share Posted May 27, 2014 Like i said, my alt is a 4 pin oval. I only use ONE wire on the harness.. The other GM oval uses 2. That must be you.
