Finding Connectors

[Kibokojoe]

I have a couple connectors that I am trying to replace but can't find a part number for them. Any ideas? As you can see they are toast

1. Three pin connector from the AC compressor

RealOEM have a page with part numbers for various plugs etc. http://www.realoem.com/bmw/partgrp.do?model=HD22&mospid=47382&hg=61&fg=15

That is for an '89 535i.

aux fan connector to the switch on radiator
Plug housing
Part number: 61 13 1 378 410
old p/n -Alte Teilnummer: 61 13 0 492 947
got one from Germany

the old one has different design for the connector in agled design. But the pins with wire in angled design do not fit to the new connector. You need straight pins. So either buy some new pins with short wire attached and resolder them, or find old cable looms and cut these off and resolder them.

Then I investigated further in the 2 and 3 pins, for example shown on the engine oil level plug. The female plug you can get from BMW, but not the other one. I also got these from Germany from Bosch, I now have 3 pins and 2 pins connectors, both sides, and the male and female pin, plus the rubber protectors for them.
Here are the numbers

Problem with RealOEM is they show male fittings but not the female. Trying to figure out which components go together is a real pain. I am thinking about using Weatherpak. They come in 1 to 6 wire configurations all I have to do is figure out wire gauge sizes. Oh I am sure there will be someone who will make a sexual reference to this response. Always is................

i have a lot of those i need to replace i was just going to order a bunch of either #7 or #8 (7 i'm pretty sure for foglights, temp sensor size plugs) and connect the wires individually you can order them at pelican parts. i'll probably use rubber electrical tape where the plug goes in this case, maybe you'd prefer to do a better job yourself...

for now i'm making do with canadian tire parts... they suck they are hard to size around the male connector.
