intermittent brake lock issues

mustang 2054. not real fammilar with these quick look. brakes spring applied pressure released .in my case. started by verifing brake release coil would magnetize whenn 12 v applied. yes put it back on . applied twelve volts to coil yes brake release therby confirm elect not hyd. it being intermittent need to chase wires.(so if anbody can provide a schematic it would be most welcome.) i failed bad looking online to locate one. / MY THINKING AT THIS POINT . is A. the fact that is intermintent and sometimes they partialy release is that my supply wire is breaking down as in will carry volatge but not a load. B. got no idea how the little brain box works? C. my dillema being is chas wire outa brain box to coil: can do physaccilay but a pain. as well as do not know what demands need to be met to relese brakes as in will a low volt seat belt. effect the brain box..LET IT BE SAID THAT JUST BYPASS THE THE SAFTEY FEATURES IS NOT AN OPTION. NOT NOW NOT EVER NOT ANYONE,

think I got it nailed. llackining a schematic physacilly traced wires pwr to brake on off switch is fed by a small module mounted to rops just behind park brake switch has ghel part # got pwr in but no pwr out. also shows sings of deformation and appears to have never been out. I can cross up pin one to pin two and brake works fine. supposition is this a brake interlock control module. when demands are met little black box with led. sends pwr to pin 4 any got the thing ordered 55 bucks. so in closining yes short red to orange pin 2 brake switch illumantes can switch back and forth to brake on brake off. module ordered 55 bucks am I gonna bypass safety features if it don't work? not a chance in hell. it will be made right back to factory spec.
