LT1 swap harness
For sale
Basic 94-95 LT1/4L60E OBD1 engine swap harness. The splices are more convenient for a 3rd gen but can be tailored to fit anything. This not a stock harness with some wires labeled and a jacked up price. It was completely disassembled and rebuilt with proper lengths and routing for a simple and clean install
Add Battery 12v, IGN, fuel pump relay and it will run. Necessary connections are marked
4L60E
!AC
!Emissions
!Rear O2
!Evap
$350
Can convert to T56 at the cost of the connectors
I build LS1, LT1, TPI, 0411 SBC harnesses. If you need something relating or just a replacement connector PM me

Re: LT1 swap harness
Rocket, maybe you can help me out. I bought a 96 caprice with an Lt1 that I have plans on pulling the motor and transmission (4l60e) and putting it in my 89 camaro RS. question is this: The harness that came with the car and computer will be used but how do i convert mine to the car itself? Thanks for any replys anyone may have.
