ECM - 16156647
EPROM - BALK
DRAC - AGQ

All your's if it'll work. I got it from him to start decoding the SGT bin and start doing some SGT chips, but to be honest, I'm not really that inspired to do em, so I don't need this ECM anymore.

Nope sure don't. I have a couple of Sy harnesses (in need of some TLC), but no SGT harnesses. ECM has your name on it, just LMK if you need it.

Coolness. Thanks again.

I have the harness covered, I guess. I have the black 24 and 32 pin connectors in my stash. I found a pin-out for the 92 CPI engine in my 92 Light Truck Emissions and Drivability Helms manual. The only wire I have to add to the existing harness is the 4th gear signal, and remove all the 4L60e wires. Other than that, it's remove all the pins from the 7747 red and blue connectors, and sort and install them in the 2 black connectors. Not difficult, but tedious because of all the checking and double-checking the connections.

T-Bone might have a SGT harness.I know he parted out a wrecked one and a crusty one.

I have the ECM and PROM from Marty's SoGT ready to ship. I also have the enginge harness from my SoGT, but I'd need some time to pull it (kinda busy right now). No problems with any of it. Only selling these parts because the truck wants boost. Email me (see profile) if you're interested.

Dave,

There is a yard out in the Palm Des. area that may have what you need, we can make a trip out there if you want. Breanna heads came from there and most things are not cut up there.

Breanna truck is running really good and she is driving it everyday. She is starting to think that 3.73 gearing and the close ratio gearbox in a 2800lb truck is not a good match. I have to finish the machining for her short throw shifter and get it installed. The new travel should work out to be about 1.5" between gear changes instead of the now 8".

I don't want to jack your posting, But the A/C is working great. It's a 1000 time better then my Syclone and will make the cab down right cold.
