Weird Female Connector by Coolant Tank

[Zambuzan]

Anyone know where this darn thing is supposed to be connected to? Is it even factory? Beats me. It's just been sitting there... lonely...
Thanks.

put your ween in it

[kronus]

the only things that color and shape on e30s are part of the airbag system

Yeah, like what kronus said, yellow connectors are usually part of the SRS system.

Your car is a 90>?

Also, get rid of that shit filter :p

'88. Non-airbag.

My '86 non airbag also has that plug, with nothing plugged into it. I am also curious to know what it's for.

Hey, I knew I couldn't be alone. Do you also have a "shit filter?"

LOL @ filter comments. Stock air box makes about 5whp more than that those cones and adapters, did test that on a dyno myself. :/

I'm guessing its all about conditioning the inlet air flow?

The stock box has a tapered horn for flow into the square AFM opening, and it's actually a cold air intake that draws from low pressure behind the headlight.

The cone is disruptive and that filter sucks in hot engine bay air.

I'm just guessing here, but could that connector be for the early-style SRS system like what E23s and similar got? Like I said, just an out-there guess, that orange connector really does scream SRS. Not a lot of info out there on early BMW SRS, not even sure SRS was optional on US E30 previous to 1990 federal passive restraint mandate.

How far back can you trace the wire? The late E30 SRS wires can be pretty easily traced back to the SRS control module location.

Put a voltmeter to the leads and see if there's 12V across them.

I thought I remember reading somewhere that there was a connector under the hood that could be used to hook up a battery tender / charger to keep the vehicle charged while it was being shipped.

Or maybe it's just too early and I'm not thinking straight yet.

I think it’s a connector left over from the brake lining sensor being deleted by someone. My ‘89 non airbag car has them and the other end of that wire goes to the brake caliper.
