So I know where everything goes basically. Now it's just some questions of order. Does the order of the injector wires from the passenger side of the wiring harness matter as far as order? I don't think it does.

Then I have two eyelet style ends on two black wires that I never remember taking off. Are these just grounds?

Then the 4 vacuum lines at the front of the air plenum by the throttle body. Matter the order of them?

Everything else seems pretty much color coordinated.

Everything is pretty much hooked up. Just a matter of bolting up, oiling up, and staring.

About ready to get my SE going with the new motor.
All that is left is bolting the transmission to the engine, bolting the engine down, putting the air box back in, putting the radiator back in, and tightening up the oil lines. Then it's fluids and an oil filter. Then zoom zoooooooooom!

I can't wait! I hope it doesn't blow up.

Now, injectors, do the plugs off of the harness have to go to a specific one?

Then another thing is about the two eyelet tips on the ends of black wires which look like ground wires off of the passenger side of the harness. Baffled me. I never remember taking them off of the harness on the "new" motor. Hmm...


OMG I can't wait.

Only "mods" are some silver paint, removed the oxygen pump and air pump, then removed air conditioning.

Yes it does matter which injector plug goes where.

#1 injector is Blue-Yellow/Brown-Yellow
#2 injector is Blue-Yellow/Yellow-Red

both grounds go on the driver side on the engine right infront of the oil filter

Remove the Cat before you run it. the cat can melt from no secondary air injection, then restrict your exhaust in 5 minutes or 5 months. I risk I wouldnt take. My SE blew because of it.

the oder i do believe does matter when hooking up the injectors. the eyelets are just grounds. make sure you ground them! there is a ground that is detrimental to the injector opening circuit. i found that out the hard way. i knew the fuel pump was running but i just wasn't getting any fuel. i found a loose eyelet and grounded and i magically had a running engine.

Well there is a long side of the harness after the 'Y' and a short side. Does the long side go towards the back?

I'm going to gut the cat btw.

So I ran the line to the cat into the intake manifold where it was again. Should I just cap this and lose that line? I've gotten two different messages about it...

Thanks. I didn't realize this thread had actually been posted. I thought in the mess of errors it would be lost.

So yea, you comin' over to do the work for me?

did you get everything figured out?

The FSM gives a gereal idea of how to route the wire harnesses, along with which wire fires which injector. There is also a vacuum routing diagram. 3 of the 4 vac ports on the front of the DC are fresh air ports, only one is vacuum.

This is a good reason to take pics during disassembly.

Yea. I went ahead and read the entire uninstalling and reinstalling section. Thanks.
