hey guys I changed the 2 coolant tubes under the intake manifold on a 99 528i.
pipes 8 and 5 here http://realoem.com/bmw/showparts.do?...38&hg=11&fg=35
not a bad job at all took me a couple hours. but i completely forgot to mark all the electric connections. I know, I know stupid of me. now I have no idea where they go. please help.
i know there is wiring diagrams out there like this one: http://wds.spaghetticoder.org/en/e39/
but I have no idea how to even read them. I was wondering if some one had a car with an air filter box taken apart that could take a look and help me out
here is the pictures
I just need help with the wires coming out of the side I think its 6 wires
There should not be wires hanging, but only plugs. Were those wires already exposed or did you cut them off yourself?

What plug or plugs are the problem? Is it the other end of that green/blue wire set? And this is a M52, correct?

In that location, maybe intake air temp sensor, more likely fuel evap valve or oil filter housing plug. The color codes are bs. Whats not plugged in already? Most have different plugs meaning male or female or 3 wire or 2 wire. They also leave the loom close to where they go. I unplugged every single one while doing the head gasket and figured it out months later by just looking at it for a minute. Your 99 may be different then my 97 tho.
I had the same duct tape job on the ccv line, dont know why bmw used such brittle/thin plastic for that piece.
Oh, I see now the car is a 99. That's a M52tu. Very different. You're just going to have to lay it all out and start best-guessing.

I'm not very familiar with the I6 since the 2 BMWs I've owned both had V8s. However, in my experience, most of the connectors are different enough that you can not plug them into the wrong socket. Also, on vehicles of this age, the wires have usually taken a set. They will usually "remember" where they used to go. I used this to my advantage when I did the valley pan gasket on my M62tu. I found that if I had to bend the wire against its natural set, it was likely not routed correctly.
anyone out there
.Try penskeparts.com, the diagrams are a little better than realoem. Also search craigslist in your area for parts cars.
You should search e39 and try BMW 528 in the search box, or even go look at similar cars for sale and pretend your giving the engine bay a good look over before you buy.
