Cut the brown and white wire from Relay 53. Splice the end from the relay side to the clutch interlock switch. Splice the other wire from the interlock switch to a ground point. Cap the other end of the brown white wire. You don't need it anymore.
Loosen the jam nut on the brake pedal and turn the large hex nut in or out until the brake pedal is even with the clutch pedal.
For the clutch bleeding, I have tried many methods. (Pressurized, one man bleeder, mity-vac) The most effective is to loosen the bleed nut at slave cylinder and get a good flow coming out. Tighten bleed valve. If pedal is still soft and releasing low, pump the pedal 20+ times and then drive it. 9 times out of 10 a few short trips takes care of it.
