Step 4
Installing The Wiring Harness
Slide the rubber plug along the wiring until it is directly
against the 4-pin connector.
Carefully bend the copper capillary tubing to make space
for the ballast. It is helpful to look ahead and see where the
ballast will mount to determine how to move the tubing. Be
careful not to crimp or break the tubing.
Line the holes in the ballast mounting plate with the holes
in the strut supporting the compressor.
