Injector harness question

Post by 2.2TLegacy »

Are the connectors injector specific? Like if you put the front injector plug on the rear injector does it cause any issues? Or does it not matter? I took out my wiring harness and just need to know if i should be watching out for what plug goes to what injector.

Yes, the connectors are injector specific. If you put the wrong one on the wrong injector it will fire at the wrong time. At least on the 90 MY wiring harness, the injector plug harness is labeled, 1, 2, 3, or 4. Not sure if they continued doing this on the later years.

Is it labeled on the actual plug for the injector itself?

It's labeled on the wiring loom

If you look at this picture, follow the connector back to the wiring harness. It will be black, and then a short silver area. This is the label for the injectors.

Other option is check the wire color against the wiring diagram. If you don't have a label, and once you've confirmed you've got the correct ones, I'd suggest labeling them :)
