Wiper Motor Wiring Harness
On almost every restoration I've seen the windshield wiper motor harness is taped incorrectly to its clip or not at all. This picture of an original 7,000 mile 1970 Shelby is a great example of how it should be done. In the picture it's hard to tell but the cloth electrical tape is 1/2" wide (most standard cloth electrical tape come 3/4" wide).
Start by wrapping the tape around the wires by themselves to hold them together at an angle (see tape in the middle of the two end wraps), then continue to wrap one end of the clip 2-3 times and cut. The other side of the clip was wrapped 2-3 times and cut. In some cases they would cross over to the other side of the clip without cutting the first side. There were many methods used to wrap this wire harness but this way seems to be the most common.
The windshield wiper harness was clipped into the far left hole on almost every original car we’ve seen.
