Hello Guys, I would like to know if someone of you have done this before or have a part# or recommendations, I have an Evo 8 2003 with 4 plug ecu, Now I bought the Haltech Platinum Plug in from an Evo 9 which is a 3 plug ecu. So I want to put the haltech in my evo 8 so im looking for a harness plug and play to mount my haltech. So what I need to do or where I can find a harness from evo 8 to plug an evo 9 ecu on it without cutting or splicing the oem harness . thanks for the help and have a great day.

 

I don't believe there is a commercially avaialble harness for this. I built one previously by buying an Evo9 extension harness and mating it to a female 4 plug ECU connector.
