i know this is not thirdgen related but i need some help. I'm considering on doing a ls6 swap in my 89 ta and i found a 01 z06 short block with stage 2 heads and cam for a banging price. The only downfall is that it doesn't come with the harness and ecm. im wondering if i can use the harness and ecm from an donor 98-02fbody and the c5's or have to use the ecm and harness z06 for that particular model and year?
