From that efi express link
*** After the pins are swapped, the red wire should be at position #2 (middle of the connector) and the purple wire should be at position #1
.
*** Slide the pin cartridge back into the plug and push the rubber boot back into place.* If done correctly the factory ECU should still function just fine.* The purpose of this pin swap is to reduce the noise that is received by the ecu on this harness by swapping the shield and signal(-) wires.
I have swapped the red and purple a few times. One way vems goes nuts and really struggles with triggers.
But it's the black wire I think is connected to the shield so I'm not sure the above description is correct.
