This harness is used with the Chevrolet Performance Parts LS & LT engine control harnesses.
This pass-thru harness plugs into the factory bulkhead connector and gives you flying leads for all the wires in the harness. This is very handy when using the Chevrolet Performance transmission controller in conjunction with the LS engine controller and would like to use the CAN leads, Tach signal, or anything else that is located in that connector. This means you will not have to cut and splice wires in the Chevrolet Performance engine or transmission harness.
Leads that are included:
CANbus twisted pair, MIL/CEL (check engine light), vehicle speed, MAP signal, Oil pressure signal, Throttle position signal, 12v battery, 12v switched, and ground.
