80's J-10 proportioning valve questions

I grabbed the proportioning valve off of a mid 80's J-10 in our local junkyard in order to work with my disk braked dana 60 front. It has what looks like a connector for a wire of some kind coming out of the top that I'm not sure of what it is. My teacher says that It is probably a wire to the brake light on the newer truck that warns you if you lose pressure somewhere. Does this seem right? Can I run with it un hooked? My plans are to plug up one of the front outputs and send a line from the other one to power both front brakes from a Y splitter that is mounted on the center of the axle (it came with the axle), does it seem like it would work?

Thanks in advance.:cool:

The wiring hookup is for your idiot light. I've got the same thing. Mine isn't hooked up, so I'd guess yours will work fine like that too :) As for the plumbing question, I'd think it'd work. But you're best to try it away from pedestrians and small animals first :-p Big animals are ok.....they're more resiliant.
