While we're on the subject of wiring, the LS2 is a Drive by Wire engine. While it can be converted to a cable throttle it is much easier th add the DBW wiring and pedal sensor. The GTO pedal sensor is about $285.00 but the Corvette LS2 sensor and pedal will work if the correct changes are made to the E40 ECM J1 harness. By the way, if you bought an engine fgrom a donor vehicle with the ECM and engine harness you are missing the J1 harness. You can get one from the EFI Connection ( or others ) that has the OBD2 port and DBW wiring with the connector necessary to marry either a GTO pedal or a Corvette pedal to the ECM. Then the Corvette pedal and sensor can be purchased for $72.00 from Pace Performance. Much less expensive. I took the Corvette pedal sensor and plug welded it to the Mazda cable operated pedal hangar as shown in the photo's giving a DBW pedal in the stock location.
