Porsche LS3 Wiring
Wiring the Porsche LS3, perhaps the most daunting of tasks was not to be taken lightly.
Wiring the engine with the GM performance universal wiring harness was very painless and simple, with each connector properly labeled.
However getting the GM electronics to talk to the Porsche electronics was a task in itself. To bring life to the factory Porsche LS3 gauges and other chassis powered units and devices, we had to strip down the factory Porsche engine harness and adapt the original sensors to the LS. This process ensured that vital information could be communicated to the car itself as well as the important task of starting the Porsche LS3 with the starter signal and alternator power. Although there are still warning messages as expected, we were able to get full function of the factory gauges, tachometer, water temp. and oil pressure.
