what do these do? (need ppl who know electrical)
first, my corvette is a 79 late model 
so im looking around the wires for the reason why my brakes dont light up any more and i noticed some plugs that are unplugged
this is underneath the dash where my steering wheel is:
plug 1:
plug 2:
plug 3:
any and all help is appreciated
thanks
by the way, i checked the fuse for the brake signals, fuse is fine. what else could it be? turn signals work so it cant be a wiring problem (at least not in the rear half of the car
thanks again for the help i know will [eventually] come

My advice would be to purchase the '79 assembly instruction manual (AIM) and track these down. The AIM will show a diagram of the main dash wiring harness installation and connections for options. Some of your loose ends may be for options not on your car, others are likely to be connections for items not working.
The GM Chassis and Service Manual will help if you can't find what you need in the AIM.
Good luck.

A memeber going by PAPAWARNER will e-mail you a wiring diagram at no cost. I don't know how to post a link but this is what it is under
Corvette Forum > C3 Corvettes, 1968 - 1982 > C3 General
68-82 wiring diagrams for anyone
Or you can just do a search - look for his screen name and go from there.

A turn signal switch can fail and cause the loss of brake lights with everything else working. I would check the power coming to the pedal switch first..

I have a wiring diagram in poster size laminated on the garage wall right in front of where the car parks. It was about $10 from Lectric Limited. Even if you get the answers you're looking for here, I'd still buy one for future reference. They are a great thing to have. BTW, mine is a 79, so if no one else gets you what you need, let me know an I'll check my diagram for you.
