I was poking around today as my brakes feel like mush. I noticed a brown wire hanging behind my master cylinder. I have a Camaro book coming so I can ID this stuff but it isn't here yet. Can you guys ID this wire?

oops... I meant round.... not flat blade style. :)

Does the boot have a small hole in the center? If so, it fits that terminal on the valve. Did the car originally not have a booster? Maybe that's why it's so short.
Mine was manual also, but the wire was still long enough to reach once I put the booster on.

It lights the BRAKE idiot light on the dash if the brake pressure is abnormal such as when the master gets low on fluid, or there's a leak in the brake system somewhere.
There's a corresponding brown wire inside that attaches to the Parking Brake switch under the dash. Both of them will light the idiot light. No offense. :)

Ok, I don't have an idiot light I guess so it isn't needed. Have the Dakota gauges. Now since I know it does nothing for me I guess I gotta figure out why my brake pedal goes almost to the floor!

Thanks Joe

Ok, I checked and yes I guess I do as well. Now what is curious is the white fitting on the valve looked like a black boot from the wire was on there as there was some black residue. But when I try to attach it I don't get the feeling I am getting that boot to fit the connection properly even if I had a few more inches of wire. Hmmm the white fitting has two lips and I get over the first one but not the second and the boot just kinda pops off

Hmm well that boot looks like it fit the proportioning valve and my Camaro factory assembly instruction manual says it is the brake alarm switch - UPC j50/a4 - power brake narness ext asm. For me the question is why doesn't the boot fit over the switch and connect as expected.
