It is just the stock harness, I cut off the extra wiring for the ac and rear O2 sensors. But other than that is is stock. I am using the fuse block from the truck also, just powered it up from the fuse block. It was cheap and it works great.

No issues with throwing codes from the missing sensors or anything? Or did you have the computer re flashed to reflect the change you made?

The computer was tuned to have those not throw a code.

Good work on the swap. Have you had any issues with the racing innovations headers?

Really nice swap, I'm doing the exact swap. Do you have pics of how you connected the gas pedal (cable)? Did you build something custom or modify the one off the donor? Tank fittings?

Re: 1970 GMC 5.3/4l60e swap

i have 5.3l finally, and a 4l60e. are the dimensions of those motor plates the exact ones you used? i don't want to deal with modifying the driveshaft if i can help it.
