This is from a '99 FBody and the harness has been gone thru by Pez (MidWest wiring guy and RX-7/LSx swapper) to eliminate and thin it out, relabel, and check for quality that it will work properly.

This is for a 6 speed manual LS1 swap (any chassis). All smog stuff is removed.
02s, MAF, OBD2 port, fuel pump, constant power, switched power, reverse lights, speedo, tach, efan signal all labeled for easy install.

$500 shipped to the lower 48 states
Add $100 (shipped at same time) for a PCM with stock tune (if you need a reflash/tune please send it to someone else to do it)

This harness simply needs to have power provided to it (from your ignition switch which is all labeled) and connect the other labeled connections. I just had the smog crap omitted. Mine does not have relays and you would need to add relays for the fan, fuel pump, etc which is pretty simple to do.

It will work with any LS motor running a 24x crank reluctor wheel and cable TB. It should be run with a T56 as the wiring for an auto on that portion is different.

I went with a Holley HP EFI instead on my swap.

Thanks,

Mark

Won't work on a pre '99. Wiring is different. (different coil packs, PCM)

Sold both items today. Thx
