Repair Procedure
WARNING: This page is about a different car, the 1994 Mercury Tracer and 1994 Ford Escort. However, it is still accessible from the selected car via links, so may be relevant.
Cut shrink tubing one inch 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. 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 oozes from each end of tubing. Connection is now waterproofed.
