I received my MacKay Power Products harness and my MS ecu witch I has sent to Fric. He tested my ecu with the new harness and installed a program.I spent less then a day installing it. My car started up first try and after a knowledge friend cacalabrated a few censors we out on the road. I'm very happy with how his harness went together and his great service. The workmanship and quality of materials is exceptional. His service is a great value.
