assembly ) and crimp them together into one end of a

27. Crimp the red male wire plug into one of the shrink
connectors from the brake shoes, and crimp the white
wire plug into the other shrink connector.
28. Heat the shrink connectors with a torch or hot air
dryer until they shrink tight onto the wire.
29. Attach the wiring from the drums to the bottom
6.25 mm (¼ in) bolt with a wire clamp and a
6.25 mm (¼ in) nylon locking nut.
