So, I was tinkering with my 83 300sd and I found an unplugged electrical line to the right of the battery. It had electrical tape covering the male end. So, I took the tape off and plugged it in. Nothing changed....wondering if anyone knows what it does.

Just to the right of the battery. It is a double male with a single plastic male. It looks as though the connected wire fits into a metal bracket.

any ideas?


PS: my windshield washer fluid doesn't spray. that would be my first thought. It didn't spray once I plugged it in, but it could also need a pump and new lines and have the nozzle cleaned.

Could be the brake pad sensor wires. PO, or hi mechanic unplugged and taped the one on my car, but left the sensors in place...

yeah, PO cut the brake sensor wires on mine. Thats probably it.

I'll run get a picture of it just in case

Sounds to me like it might be the line from the EGR computer to the module on the PS side of the IP. Is the plug black, about 3/8" diameter and kind of a tapered bullet shape?
