    :ears: Anyone know where the ESC connector is on a 1988 v3500, or have a pic?
    I will need to disconnect it to set my timing, and I know they say it is near the blower motor on the thirdgen website. But either I looked right at it and didn't recognize it, or it must be somewhere else on our trucks.
    Thanks
    Bob

    typically it's a one wire plug that is located near the master cylinder/brake booster. I believe it's a brown wire, but it's been a while since I've set the timing on my motor. hope this helps, also it might be inside one of the wire looms if it's never been set before.

    On my 88 harness its right next to the firewall connector, brown wire with a black strip.

    On my 94 truck its under the glove box, same color wire.
