Sure hope this is in the correct forum,the problem is I am not a wireing wizard after installing an LS3 that I ordered from GM performance along with a new gas pedal and ecu and wire loom into my 2001 Trans Am after the bottem end let go.I have been able to start the engine but am stumped as to where to tap into the wiring to hook up the gauges such as oil pressure,collant temp.tach etc.I need the wire colors locations and if possible a wiring diagram as I stated I am not a wire wizard,PM me if you would like.
