I did the conversion twice. And about to do one more. It's a bit time consuming as u need to make a wiring harness(use wire loom, looks original) you will need to deem the wires through the firewall using the stock harness location, remove your old ecu and then need to swap a few wires around in the master plug but be careful. I had a few wires "jump" out and if I didn't have the manual I woulda been fooked! I bought my ecu and mass air meter in a kit and the provided the pin connectors. You will need 3 or 4 factory pin connectors. If u can't get any use the ones for the thermactor pump and components. Takes a bit of reading.
