    what does this plug into?

    so i got my 87 325e all put together (after buying it with pretty much no front end) and i keep stumbling across this plug.... i looks like it should plug into the radiator for a temp gauge but it's not long enough, and i already have that plugged in... it's right below the driver side head lights... any suggestions? the ac is on the other side of the car...

    looks like the plug that goes into the radiator side on the passanger side.



    edit: i have the same thing on mine just free sitting haha. always wondered what it went to, but never cared enough to look.

      i think the temp sensors are on different sides on the e and is (your sig indicates you have an is, or at least an i) and i know the coolant tanks and some other stuff are flip flopped between models... but yeah... weird little bugger, aint it?

            I have one hanging on both drivers side and pass side of my car and I've been perplexed by it. Always felt ashamed I didn't know what it was for... maybe I'm not alone.

              I have this same plug just sitting there and never figured where it went. Does anybody know?

                  Horns? Foglights?

                  I have one two-pronged plug hanging next to my fuse box and have no idea where that goes either.

                  Good luck.

                    those look like foglights to me.

                    in the future, turn 1 thing on inside the car, and then use a multimeter to check the wire. you will eventually find it.

                        It's for the auxillary fan. Is yours functioning?

                          Since it's for the aux fan is there a way to set up the electric fan to run off of it?

                          I have two three pronged neither connected to anything on my swap.

                          And I have two two prong, I'm fogless thanks to some PO so i now just use the fog light circuit for my fan switch.
