that one doesnt' go to the idle air servo hanging under the throttle body? there should be a plug for it on the backside of it. I kidna remember that connector bieng blue for some reason. that particular style connector is only used for the four main injectors, the cold start injector, and the idle air servo. I think the turbos used the same connector for the cruise control, but I'm not 100% on that.

what, exactly, did your harness come from?
