Engine Electrical Help!! (PICS)
Man, I got myself into a bind here by not taking pictures of where my wiring harness went when I took it off. So now I need some major help putting it back together. Most of the plugs are obvious, but then there are some that aren't so obvious, as well as ones that don't seem to attach to anything at all. And I've tried aligning the harness like 10 different ways to reach all the connectors and I think I finally figured it out now.
So here's my question, does anyone have a diagram, or a set of pictures or something that show how to put it back together? If not, can someone decribe it to me? BTW, its an 89 TII
Heres what I think I figured out so far:
1)If you were to lay the harness on the ground, and stretch it out in a line as far as it would go, the furthest connector out is the one that goes to the ACV (which I removed), correct? The Clip previous to that one goes to the rear of the upper intake manifold, and the two before that go to the rear rotor injectors?
2)The branch off before that one is one I am totally lost on. I think they go somewhere near the rear rotor spark plugs and side of the engine, but im not sure. There are also 2 little o-ring spades on this one, I'm guessing the bigger one just needs to be around a bolt somewhere on the block, but I need confirmation on this one, and the little one I have no idea?
3)A few inches before that is the set that goes to the front rotor injectors, as well as the ones that hook to the back of the water pump? Since I took this picture, I managed to break off the round black one that goes to the back of the water pump. The break is right up to the end of the connector, so I cant strip it and reconnect (). Do I need this part?
4)Sprouting off at the same place as #3 is the solenoid connectors. They are connected to the matching colors, however, I still have the dark green and bright green ones which I can't find anything to connect to?
5)Im guessing for the most part these go to the upper intake manifold, to various connectors. But it seems I have a few extras? Also, in the pic, on the bottom right of #5, is a lose wire. I remember the clip breaking off when I pulled it out the first time, and now I can't find it. What is this clip for, and do I need it?
I know I sound like an idiot, but Im just so stressed trying to do all this, and its my first time putting an engine back together, so I'm totally clueless. Thanks for any help you guys can give me. And sorry for the long post.

OK, here we go!
#5 looks to be TPS & metering oil pump (these you can worry about last)
#4 is all the solonoids which you seem to have connected, that green circled plug is a test connector (3 pin) and the other green I don't know.
#3 is your water thermosensor and your secondary
injectors
#2 looks to be the air thermosensor (located on the throttle body) and your primary injectors (I may have these reversed, but I think that's how it went)
#1 I don't know about.
Anything else?

And #2 they go to both primaries and not the rear primary and rear secondary?
I have em on wrong then.
Also, which green solenoid is a test connector? The bright green one, or the dark green one?

I might have mixed the injectors up, which is quite possible, you should be able to tell fairly easy when hooking them up, as you'd have to stretch the primaries plug to reach the secondaries, so it should be obvious at that time. My o2 sensor was located in group #5, which is probably the wire you broke off (single wire, black) That white connector is your BAC.

really? That looks exactly like my BAC. Do you have a series 4? I think the series 4 is just like a injector plug, on series 5 it had it's own design (pictured above) Which could be the confusion. That little tiny plug on group 1 looks like the plug that goes next to the oil pressure sender (oil temperature or oil level?) It's a round metal thing sticking out next to the oil pressure sender, it sort of looks like a tiny finger or something, and it just gets pushed in ontop of it.

I think I got group 1 all figured out. The 2 big grey plugs are injectors (which ones I still don't know). The little black plug goes to the ACV, and the white plug goes to, god I don't know what it is - a little tube thing bolted onto the back of the upper intake manifold. Right next to the secondary rail.

I'm pretty sure those are the secondary injectors, as they seem to be pretty long and far apart from each other (the other two should be relatively close to each other) #4 can be ignored, #3 I'm not too sure about, can you get a different view on that?

Group 2
1)I bolted this to the block under the vacuum spider stuff
2)The little thing next to the oil pressure sender (square spade screws into block)
3)To knock sensor on front housing
4)Something near TB
5)2 little spades that come out of TB
6)Bolts to the bracket that intercooler is held to (little bolt on the side)

Oh, damn you're right. Whoops. It's the ASV (Air supply valve) Dumbass me Anyway..... You know, I'm starting to think that the short injectors on each of your two sets are the primaries and the longer ones are your secondaries (my harness is completely different on the injectors) but it seems to make sense. I don't have apic for group4
