We have installed a K20A2 in an ex-IMSA GTU Dodge circa 1991 with a turbo.
In the final hook up phase now and we didn't get the complete wiring harness as the O2 sensor goes through the body harness, this is aggravated by the fact that the O2 sensor has two black wires a green and a white wire, the shop manual shows four completely different colours.
Can anyone confirm if these are used in the same way as a regular heated Honda O2 sensor?
Any help will be greatly appreciated.
