8th civic 2011 compustar cm6200

The CM6200 has internal relays for the ignition, accessory, and starter, but any 2nd ignition / accessory / starter requires the external relay. The new brains that are supposed to be release hopefully soon (but I can't find any information on them) supposedly will have internal relays for extra circuits. The black connector is the main connector. DO NOT CUT THAT OFF. That will connect into the Compustar brain. The 3 pin blue connector is the one that just gets cut off. I'm not 100% sure what the point of that connector is.Kenny

that's just it - there's 2 black female 20 pin connectors; one connector at each end of the wires. The connectors are identical in pinout, just a different size & shape of connector? Of the 20 wires, 17 travel uninterrupted between the two black connectors, while the other 3 are pigtailed a short distance and then terminated with the blue female 3 pin connector of which you speak of, and then there is a supplied matching male connector with longer leads for those 3 wires. These 3 wires are fine to use because they are empty wire leads, but the remaining 17, you'd have to choose one connector and cut the other one off in order to have some bare wire leads....

Sounds like a fluke harness. I'd pick the harness that plugs into the brain and then cut the other one off.Kenny
