I have a 2.2 4cyl. engine now and have access to a wrecked s-10 with a 4.3 for a good price and I want to put the 4.3 in mine. I know what is involved, but I am having trouble with the electrical stuff. I know I need to put the ECU from the 4.3 in my truck, but wont that mean that I have to put the 4.3 gages, cruise controll stuff, and everything else thats connected to the ECU in my truck, or will the 2.2 stuff plug into the 4.3 ECU. How does all the wireing from a 2.2 t a 4.3 swap work?
