Brake warning light - Proportion valve wire connection ?

Thanks all for your time! I don't know why the prev. owner placed it on the front post? I moved it to the center post tonight but need to bleed the system before I can drive it.

I'm guessing he plumbed the lines correctly as the brakes seemed to work pretty well with nothing that felt like it was messed up. (Other than the warning light comming on whenever you pressed the brake)

The plumbing is not as pictured above but I know different years/valves were plumbed differently also.
