H22a4 wiring harness diagram - For the vtec , i might count on you want the ecm to go with the 97 motor, and if the ecm harness is missing the ones 3 wires (2 vtec, 1 knock), then you have to run new wires. I'm able to come up with diagrams, and help with pin place. Matt. For the codes, p1259 is vtec malf, set due to the fact the solenoid and transfer had been now not used with the original motor. The alternative three codes need to have nothing to do with the change. The pins at the ecm are the equal for every motor. I'd test the ect, iat , and egr valve raise sensor. All of them proportion the same sensor floor (inexperienced/black), on the car side this sensor ground is green/white. However pin places must be the same. You may discover this wire in the connector and verify this. So you say that even though they're all specific colorations and such, that the plugs and pins in them should be the identical? As some distance as going to the same places? If so, then why the codes?. As a ways as "missing only 1 twine", i'm no longer sincerely "lacking" one at the engine aspect, i just supposed it as, out of all the wires in the plugs on the engine facet, i handiest have the one empty spot, in which as i've four i agree with on the car facet(three being at the start non-geared up).
I should have the ability to help you with wiring diagrams from either automobiles/ 12 months motors. It is probably some paintings to dig through diagrams, however i'll try to help you with the motor to chasis connectors. Inform me where they may be, how many, and as tons data as you could deliver me. Matt. K, i'll see what i'm able to do. Unluckily , the wire diagrams don't show the ones connectors. Did you convert the ecm also? And in order that i'm clean, the engine facet has 3 wires that the automobile facet doesn't. What do you suggest, you "are missing best the one cord".
