1998 tahoe alarm and reverse wire

Ref the reverse light; use parking brake, turn on ignition not engine, place in reverse, go back to the light cluster and test for which wire, when you find out which one, try and pick it up in one of the floor looms at the kick panel. Alternatively if auto it might be under the shift lever.

xk06 will work when flashed with PLXR 3.00 firmware

GM usually uses a light green wire for the backup lights, you may be able to find it at the park/neutral trans position switch on the drivers side of the trans
