Hi all,
I have installed an E30 M3 instrument cluster into my 325is, and I'm having a lot of trouble getting the oil temp gauge to work. I have been basing my wiring on the diagram here http://www.sixinabox.com/oiltemp.pdf
So what I did was splice into the green/white (+) and brown (earth) wires on the blue plug in the back of the cluster, and then ran a wire into the engine bay to use for the temp sender. Here's the thing, once I fire up the ignition the needle blasts straight to maxmimum, and stays their regardless of whether I ground the temp sender wire or not. Now it seems this was likely to happen because by the wiring diagram it has two earth connections (brown wire and temp sender)...?
I'm really hoping someone else here has done this cluster swap and can tell me what they did. I'm confused!!!!
Is the M3 sender a single post temp sender, or a dual post? Perhaps what is supposed to happen is that instead of earthing the sender wire, it's actually supposed to send back a +ve signal?
Cheers,
Andrew.
