Repair Procedure
WARNING: This page is about a different car, the 1997 Ford Probe. However, it is still accessible from the selected car via links, so may be relevant.
Cut shrink tubing 1" longer than butt connector. Slide shrink tubing onto one wire end first. Insert pre-stripped wire ends into proper size butt connector, and crimp connector using appropriate crimping pliers. See Fig 1 . Slide shrink tubing over butt connector, leaving 1/2" of tubing on each side of connector. Using heat gun, hair dryer or match, heat tubing until it shrinks and adhesive flows from each end of tubing. Connection is now waterproofed.
