E30 M20 Wiring help in orleans?

Hey guys, took my engine out 2+ months ago and stupid me forgot to label the connectors before unplugging. Now the engine is back in the car however I dont know how to plug everything back. I did what I can but there are so many clips that look alike. Can anyone come and take a look and help me please?

Power steering and A/C havte been removed, power steering only temporarily but still... too many clips for it just to be those two.

I also need help with the cooling system in case I dont do it properly.

Thanks everyone.

They might look alike but really they only fit one way. Even the injector wires are cut to length so that should be dead easy to sort out.

Just start by laying the wiring back along the firewall and connect the parts you know, nothing stretches so should all make sense at that point.

Look at some pics online on google or something if you need to.

That's what I did. I connected most of it now just down to a few clips that I don't know where to plug into. Does anyone know how many clips go into power steering and ac? That way I can rule out a couple.

Also near the starter there's a ground wire that comes out of the harness. This bolts into the block right? The hole that's there is stripped so I can't thread anything in there.

For the cooling system: you have two plugs which are connected to the injector loom. One brown and one blue. the brown I believe is for the temperature gauge. they are different so you can't reverse those two. the other cooling wire goes into the side of the radiator. This one tells the aux fan when to come on when using the a/c. should be on the left side of the rad. the aux fan plug is a heavier 3 prong plug which runs behind the left side headlight to plug into the receiving end of the fan.

a/c should have two plugs. A green one that fits into the receiver dryer and the other for the a/c compressor. Again these are not all the same. Each is different. You just have to go through them one by one.

hope this helps.

Most are colour coded, or have a set number of pins, or a set length.

See thats my problem... mine aren't colour coded, they're all black! But if you guys say most of them should only clip into one receiver because theyre shaped differently I'll go over it today again.

Thanks for all your help.
