Difference between 1g and 2g ECU Harness?

[projekz]

Is there a big difference between the 1g Ecu harness and the 2G. Reason why I'm asking is because I want to know if a HKS VPC made for the 2G will fit my 1G. Thanks

The harness will not be plug and play. A few years back I had a diagram of the wires that needed to be used on the 1g harness but, I don't have it anymore. Best bet is to find someone with a 1g VPC and have them tell you the wires you need to use and where they need to go on the VPC unit. You should look into getting a 1g chip as well.

1g ecu's have 3 plugs and 2g ecu's have 4 plugs. Sounds like a lot more work than it's worth.

It taps in like an AFC.....Not a lot of work he just can't use the harness that comes with it. WTF
