What is this harness? It was unplugged after I let the dyno tuner shop fix a popped injector after a dyno run. One wire plugs into the EGR and there is an extra "end" that isn't plugged in. And other wires of course.
That's a vacuum connector. I can't remember where they plug into. I'm sure someone will know. I wanna say one goes to the smog pump area, one to egr and one to the upper intake. It's only a guess though.
One to Egr, two for the smog pump stuff, and I believe one goes to the intake like stated. They should go over to the valves on the back of the passenger side shock tower.
