I have a 1996 k1500 with the 350 Vortec. My alternator is slowly dying. I want to upgrade to the 140 amp alternator. I am told I will need a new belt and a new wiring harness adapter. Which wiring harness adapter PN do I need?
We have the 145 amp large case AD244 series that bolts directly into your vehicle without need for wiring harness adapter, your plug matches the alternator.
