I have a 67 Mustang That I am doing a Coyote swap into. I have in my garage the coyote motor and complete harness computer steering column gas pedal ignition and just about anything else I could think of to get out of the donor car 2012 Mustang GT including radiator fuel tank and all. As far as the front suspension I have purchased the RC-107. I have read that it is difficult to use the Harness and computer from a donor car. My question has anyone used a donor car harness and electronics or would I be better off buying the Coyote Swap kit from FRPP?
