This harness is everything it says it is. All the plugs match to the trans/alt/main harness and such and includes hookups for automatic trans as well. The only gripe I had was that it doesn't include any list of which plugs in where, so if you don't have the fsm or the old harness to check with it may be a bit confusing at first All in all a great product!
