  • OBD2 wiring for race cars

    Im going to keep the AC pressure sensor for wideband feedback into the datalogger. I am not sure what some of these other connectors are for, and I am also not sure how to go about the fuses and relays just yet either. The big connector that is cut off is what would have gone to the power/relay distribution.

    1st pic looks like ICM power,
    2nd is AC pressure input
    5th, don't know
    6th looks like ICM control, or EGR
    I'm not too sure what the others are, the last one has the MAF leads, oil pressure sender, knock sensor, and a/c compressor connectors pictured with it.

    Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.

    I get bummed out every time I type "titties" in the search bar and nothing pops up....

    Built not bought, because bolt-ons don't...
