| Post subject: | Engine Harness Question |
Hey all, Been doing some reading of posts and the archives, basically looking to clarify before I try to purchase a harness. I'm running a 4G61T setup in 91 Colt, I have a 1990 DSM ECU, so I'm in need of a harness. I don't plan on changing over sensor's or anything, so from what I read I need either a 1989 Colt/Mirage turbo Harness or a 1990 DSM harness and as a result it will be just plug and play? A friend of mine gave me a harness, but a few plugs are cut so I'm not sure if it's a 1990 or 91-94. I remember reading somewhere how to spot the differences but I can't find that post right now. Though plugs are cut on the DSM harness, I still have factory plugs from my original 89 turbo harness that I could wire if the harness I have is a 1990. Would anyone be able to help me by looking at a picture of the harness? Or listing the key differences? thanks in advance Jim |

If you can post up pics of the throttle body connectors, the cas and the coil I can tell you if its a 90 or 91-94. Also the 90 dsm harness is not plug and play on a csm. Only a turbo c/m harness from an original turbo car will be. The dsm harness is close on the engine side but its completely different where it plugs into the dash harness at. |

Thanks for the reply Mirageman, I'll grab some pics tonight or tomorrow when I get a chance. So will a 90 ECU and 89 mirage/colt turbo harness be plug and play in the csm? That's what I would be looking for I would say  unless the free harness I have is useable with minmal hassle.Cheers, Jim |

if the harness plugs directly into the isc and the cas.. then its a 91-94... if the wires actually some out of both of them then into a plug then its a 90... also look at the coil pak..90 has a square plug..91+ have triangle ones. Steve |
