1995 Acura Integra Brake pedal switch & h

I've been trying to install a new 791xv all day in my friends integra, everything is almost done, i tested it and remote start works great everythings working great...but i'm having the hardest difficulty finding the positive brake wire and the horn trigger, it says GREEN / WHITE wire above the pedal but i cant get to the wire, i can almost see a blue plug behind a black loom of cable but i can't get to it. does anyone know if theres an alternate location or alternate wire to get for the brake wire, perhaps a wire going into the fuse box under the steering wheel i also cant find the horn trigger wire, i probed nearly all the wires i could find on the steering wheel and none went up or down when i pushed the horn, i cant find the gray or blue/green wire, is there a special panel beside all the plastc to remove?

just got back from kick, tested 3 green wires on lowest bottom loom, 2 small awg 1 fat one, but none of them +12 when i pressed the brake wire...is this the right loom?

it's up high...look for a big brown plug bolted with a 10mm. kinda behind that, and up!

i got it on my car no problem.....disconnect the plug at the switch to get extra slack or just go to the kick and get the wire there.....
