I've got a '99 E300TD. I had to remove the engine and most of the left front components so some frame work could be done while I was repairing the engine. I'm almost done reinstalling the engine, but I have one 'orphan' connector that I can't find a home for in the left front. I've accounted for the engine harness, the AC, the washer bottle, lights, etc. The connector has two wires - brown/red and brown. The connector is the same size as what goes into the receiver/dryer temperature sensor. The wiring runs as a pair back up over the wheelhouse, and then merges with another cable by the brake cylinder. I can't find any clues on either "alldatadiy" or on "EPC/Startek", and I've looked at all the schematics I can lay hands on. Any clues?

Posting a picture will probably help identify.

Got a few pics.

First - the plug itself - two views:




Now, showing the location and length of lead. This is in the front left corner by the oil cooler and A/C receiver/dryer.

Complete guess - headlamp washer wire but car doesn't have washers? If so, there should be another...

I think is the external temp sensor. search in your front bumper driver side grille

You mean the broken, scraped, shattered pieces of plastic that used to be a bumper cover? The scrap plastic that got manufactured when my teenage son hydroplaned, spun, and wiped out the front corner, starting me on this adventure?

BTW, the way he's paying this back is physical labor - he's contributing sweat equity to rebuilding the car, and as a side measure, learning about auto mechanics.

I have an outside air temp sensor - looks like a mutant alien **** probe - in my wiring harness waiting for the bumper cover re-install. The only thing I can think is that maybe the previous poster is correct - it's the wiring for the headlight washer, which isn't installed. The problem with that theory is that the wiring diagram calls for different colored wires for the HCS.

I'm at a loss here.

Just a guess, try brake wear indicator(wire would be coming from the left front wheel up the wheel-well) or hood latch switch at the latch, color seems about right for either one.

Is not the headlight washer mate, i have headlight washers in my car and not have this wire. i only seen this connector style in the external temp sens/presostatic ac valve/ ac compressor clutch/US spec bumper side markers.. no more than this :S

Edit: Oh maybe is the alarm switch under the hood latch (driver side)

That was it. Couldn't see the connector from above - and since I'm over 2m tall, I don't bend down to look at the underside of the hood connector often
