can someone show me a picture of their functional temp switch harness, photo inside

So im outside trouble shooting my over heating issue, and I find this harness and man...it looks like six pounds of sh*t in a 5 pound bag, its taped together and falls apart in my hand, the brass on the temp switch looks to new to be broken but there is a change the ASE master tech (joke)who owned my car before me could have mixed up the wires on the temp switch
so can someone please reply a picture of their temp switch harness so I can compare against mine,

Pinout from 1989 535i ETM.

colors:

Connector X87, 3-pin connector.

1=Brown (Ground)

2=Violet/Gray

3=Black/Gray/Yellow

Pin locations:




In your photo it looks like you are missing the plastic cover on the back of the connector. That is why I drew the pin locations for you, use the notch in the plug as a reference point.

Good luck man. Hope it helped.

EDIT:
Darn beat by a few minutes. Oh well, good for reference.

ya about that, I saw in the manual that they say remove the radiator and bend back the a/c condenser, when u bend it back the fan will come with it, so then you don't have to remove the bumper

After doing the job, I can tell you that I would rather remove the bumper and go from the front any day, especially because of how hard it was to get the old rubber grommets to let go of the brackets that they were in.

I havn't done either way yet, I think I would prefer to remove the bumper than drain the radiator and risk losing my freon

Hello there,
would you have a link to where I can find this temperature plug harness by any chance?

I switched my radiator a few days ago, and when I was disconnecting these plugs, the plastic cover cracked in pieces, and the plugs themselves are now damaged. I have looked up the part, but there's nothing that looks like the actual piece you have in the picture.

I followed the wire and it seems like it is a long one. How difficult is that to install a new one?

I would immensely appreciate any advice so I can take care of this and not jeopardize my system.

Thank you much in advance.

The double temp switch is on the right side of the radiator, near the top. The double temp switch's harness connector would also be hanging around there. There should be no other loose wires there - everything else would be connected to something (headlights, foglamps, a/c switch, wiper fluid reservoir motor.)

It should be damn easy to find this.

The double temp switch can be removed from your old radiator and fixed to the new one. Use a wire brush and clean the threads and tip of rust before installing it into the new radiator.

The switch itself (what screws in the right side of radiator) is good, but what is damaged is the plug the connects to the switch. Mine is a triple switch, so I would like to know where to find it (if possible at all, please provide a link to the plug harness, I can't find it online)

I'll try take a picture when I have a chance.

Thanks fellows!

You will come across more than that eventually. You have 3 choices:
1. Live with it
2. Go to a junk yard & cut off one, same plug is used everywhere on the car just different colors for identification. Think the window motor plug is the same, which is what i would use because it will be less brittle than the ones in the engine compartment.
3. (See attachment) found this the other day comes in different colors. Cant remember what its called.

Thanks, Paul!
So, would I basically be able to use this here: http://www.bavauto.com/assets/imglib500/61130007441.jpg to replace any of the three if not all three wires?

Paul is right. Goto a junkyard and cut off that piece and use it on your car. There is no other way.

Anyway this is not a mission critical component (the plastic connector housing itself). Just tape it up when it is on the double temp switch and you are good to go. Whenever you get to a jy for car stuff (maf, ecu, original ceramic fuses, late model gm, switches, instrument cluster, m wheel (good luck), ignition coils, a/c switch, wiper motor, fog lamps, front and rear bumpers ) you can also pick this up.

No the link you posted is not right.

The front of the connector is crescent moon shaped so nothing else will fit. What you've now got is ugly but perfectly fine on a permanent basis as long as you tape it up or wrap that in some cling wrap to protect it from dirt, dust, water, and accidental impact damage.

2nd that, they have a 90 elbow. Also I'll correct because I've just realized there are 3 wires, I was thinking 2 wires (there everywhere). So go to my second option, the junkyard. Here's a pick of my 27yr old one, so I'm sure you will find a half decent one. If you do find one cut as far as you can from the plug in the junkyard one & as close as you can to the plug as you can to yours. Makes it easier to remove the plastc liner off the wires & to solder + the extra length is always helpful. BMW made it to close of an exact length.

Also I will be in the same boat if i ever have to disconnect mine.
