Brake problems

I have a 1990 cherokee 4wd that lacks brake pressure. i have changed the booster, master cylinder, bled all lines and topped off on fluid. i think it is missing a elect part on or around booster. could any one who has one send a pick of the elect. lines (more importantly the box that connects on the brake elect. lines.... thanks!!!!

if it's non abs, the only electrical plug is on the brake differential block a.k.a. proportioning valve, between the brake lines. all that does is sends a low fluid signal to your brake light on the dash.

did you change the brake differential block when you changed the booster/master?

also, did you happen to change out the calipers? maybe they're on the wrong sides.
