Hi! I would like to share you guys the way I did my 2g Ecu jumper harness when I was running a 2g ECU on my Colt, as most of you know this will work for EVO black box ECUs as well...
Parts needed:
*White section with pins of any 1g type ECU
*Set of the 4 yellow plugs of any 2g type ECU
*Set of the 3 yellow plugs of any 1g type ECU (this is a extra set of plugs not the ones on your car)
*Heat shrink tubes and black tape
*Very tiny flat screw driver (this will be useful when you try to take the wires from the yellow plugs)
*Soldering kit
*OBDII plug from any Mitsubishi car
1.-You don't have to destroy your own 1g Turbo ECU if you don't want to, what I did is that I went to a local junk yard and I took off a 1g non turbo ECU, once that you have the ECU opened then just cut the white section pin by pin from the back part, the 2 screws holding this part on the board may have some weld so just cut those spots, this is the way I got the white part from the junk yard
2.-Next step it's cutting the pins to the same length and make them straight like they look on the right part from the top pic
3.-Take off all the wires of the extra set of 3 1g type yellow plugs, here you can help yourself with the tiny screw driver
Here is the idea:
You hook the extra set of yellow plugs to the back part of the white pin section then you skip soldering wire by wire (which is difficult), here you can start doing the jumper harness in the way you choose (2g ECU, EVO VIII ECU, 3G ECU, etc.)
Final product:
With the OBD2 plug attached
Well I hope you found this way helpful, this is just the way I assembled the jumper and I decided not to include the pin by pin steps because there are different routes depending which ECU you choose...
