I have compiled a list of all the locations, colors, and wires for shift lights for the 96-97 LT1 f-body, all LS1, all LS2, all LS6, and LS7 engines in the GTO, F-Body, and Corvette. Hopefully this will help those when wiring in the shift light. All of the connector #’s, pin #’s and wire colors are at the PCM. All of this info was copied from the engine controls schematics from GM’s service website.

IGN = Ignition voltage for your power wire
ESS = Engine Speed Sensor Signal for your shift light signal wire.
