Working on a 2001 2wd with the 4.3l V6. I can't seem to find where the BCM ground wire is connected to on the frame. I have been looking for pics or diagrams, but nothing. Any info would help. Thanks.

 

I looked in alldata and I can't find a diagram. All I could find was connector views. Only one connector has grounds. If you think you have a ground issue, you could always try to ground it yourself. Below a connector view with a description of each pin on that connector.

Brown Connector

 

There are two grounds from the BCM that run into splice pack S202 and then to grounds G200 and G201. G200 & G201 are located just above where the main bulkhead connector goes through the firewall on the driver side dash. S202 is located in the wiring harness above the accelerator pedal.
