LSx swap harness

Hi all,

I have a swap harness that was built by member Pocket for me back in 2014. Never took it out of the box. Here are the specs he built it for:
Year of 3rd gen: 1991 RS
Original trans type: T5
Original EFI car? Original TBI car, changed to carb'd ZZ4. I'll be running a single Walbro 400 LPH pump in the stock third gen tank for now.
Year of PCM being used: Planning on 99-02
PCM location: Stock 3rd gen
PCM routing: Hidden under HVAC box and mounted under the dash
Trans type: 4L60E
Block type: GEN III
Intake: LS6
Throttle Body: Drive by cable
Injector style: EV1
MAF type: Probably not going to run MAF, but if you could pin for Fbody 3 wire just in case that'd be good
MAF location: Stock Fbody near TB
AC: 4th gen low mount
Emissions: Delete
Rear O2s: Delete
Coolant gauge: Use 98 Fbody CTS in driver cyl head
Alt: Fbody 1 wire
Alt Location: Stock Fbody
Number of fans: Dual (4th gen setup)
Battery location: Drivers side
Relay center location: Stock near booster
Note, back up lights run through the engine harness

Obviously, this could be modified as needed by the buyer to fit the application. $500 shipped. Let me know if you have any questions!

Payment sent.

This should work perfect for my 91 LSX swap with a few minor changes.


Thanks!
