I need help hooking up my 95 blazer auto tranny to a 97 s-10 truck that had a 2.2 in it. i changed the engine harness and computer but still has stock dash harness with no tranny plug. can this be spliced in or do i need to change the dash harness too. the motor is a 4.3 vortec and it seems to be running fine. so if anyone can give some advice on this issue it woul be most helpful to me.
You need to manuals with wiring diagrams. You need the one for the truck and one for the donor vehical. Then stat tracing wires and meld the two harneses. I thought that you would have had to build a harness to make the engine run. The trans should be the same. I can't rember if the trany computor is seperate or integral to the engine comp on either unit you are using here. Good Luck
