Tbi timing

[fatbob]

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 mine it was by the brake booster, it is a single wire connector in line in the loom would post a pic but i am 300 miles away from my truck right now

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.
