Your T5 wont live long behind the 5.7 unless you are easy on it.

Here are some threads that talk about what you are doing.

So as far as the swap I knew I was going to need the wire harness and ecu out of the 91 and a memcal chip programmed so the 5.7 will run correct with the t5 is the c200 connector the same as the 89 or does the dash wiring need to be swapped as well just trying to figure out everything I need out of the 91 so when I'm done stripping it I wont be like oh I needed that too lol thanks for the info so far and Pauly C the t5 is only until I get my hands on another t56
