Alright, I'm swapping a z6 mini me into an 89 si that I just picked up that has a hole in the block. I had put this motor together a while back and never did anything with it so it's found a new purpose, along with the harness I picked up for the swap. The harness I have is a dx harness made for swapping to mpfi and obd1 at the same time cleanly. My question is could I make a jumper so that I could use the dx engine harness with the Si dash harness? If so does anybody have a diagram of the plug that connect the dash and engine harness for both the dx, and si?
