Thanks guys!
Here I am tackling the LS swap wiring harness. This was an OEM harness from a 2000 model LQ4 that I modified.
And here it is ready to go under the hood.
Running the harness. Don't worry, I recently got a new phone that takes much better pics. Some of these are terrible!
Here is the speed sensors I like to use for older transmissions. It lets the cable pass through so you can still run the original speedometer but also give the ecm an electronic signal to work with. In the pic I have already soldered on the gm harness end so it will plug into my harness.
