    it would help if you mentioned what year model truck youre doing this swap in ? there thousands of threads and how to's as to doing a v6 to v8 swap. if your truck is a 99-02 then you want a 99-02 harness if its a 03-06 then of course you want a 03-06 harness ! but mind you you can use any motor up to 06 which have the 24x reluctor wheel on the crank ... few others things are involved but nothing that cant be complished
