    Bumping, harness is now 100% and 4l60e converted (kept it using stock colors so there is no confusion), and I have a tune flashed in that'll run a stock 5.3/4l60e, minus EGR, AIR, VATS, and Rear O2s.

    I also have the ISS harness available for anyone looking to swap in the 4l80e, complete from PCM pins to ISS plug.



    Injectors and ignition is over to the left, trans, O2s, VSS are coiled up on the bottom, and the alt, TPS, MAP, IAC, MAF, Crank and cam angle sensors are on the right, connections to make to the vehicle are up top. The OBDII is soldered in as well, set up for under hood mount.
