Poor Braking

I have been trying to sort out a braking issue in my 78 F150 4X4 with an LMC disc brake conversion. Last night I got under the truck and discovered the disc brake pressure warning switch was disconnected and the lines run pretty much direct from the MC. I am thinking at this point I need a different pressure valve. I called LMC and the woman although nice could offer no help. She said they have no technicians, they are just a warehouse....

What do you guys think about the switch/valve?

You would want a different proportioning valve with rear discs than with rear drums. A lot of people go with adjustable aftermarket ones.
