Hi all,



I have been searching the internet and am having trouble finding the answers, so I thought I would ask here. I am hoping that someone using the same thing can help.
I have a Blueprint Engines LS3 376 with a 4L70e transmissions with a USShift Quick4 controller. The kit included everything but a wiring diagram for the engine harness.

The USShift controller needs 3 connections: Power, TPS, and Ground.

Two complications:
1. They say to break into the ground wire from the ECU AS CLOSE TO THE ECU AS POSSIBLE. Is this really necessary? And if so, how do I find which wire that is?
2. Which wire of the 6 wires coming out of the gas pedal is the TPS signal? I found a pin diagram but it seems to have two position wires.

Any help is appreciated.
