Hi i have a 302 efi out of a 1989 ford e150 econoline auto the engine and O/D gearbox will be fitted in a f100 but the problem i have is i am using all the econoline wiring harness but i have managed to snap a pin on the ecu number 60 any idea what pin 60 will i have problems.Or can i use another ecu maybe a standalone one if so what will i need and who will sell one.Or should i swap the efi for a carb thanks part number on the ecu i have is A9J E9TF-12A650-AS2A

 

Pin 40 and 60 are the main computer grounds and they're in parallel so it shouldn't make any difference that you lost one of them, try it out and see what happens. If it does present a problem then any 5.0 truck computer for a manual or non computer controlled auto transmission will work.

 

Those connectors are known for being brittle as they get older. I had to buy a new one, found on eBay.

Paul...Since 37 & 57 are also parallel, would it be OK to leave one of those disconnected if there was a problem in the connector? Or does the PCM need both of these power feeds at each pin?
