Splicing Headlight Wiring Connector Issues

From what I see, a ring or any other v screw or 1/4 inch spade terminal can be used to function the same way as the expense and hard to get Toyota specialty butt connectors.

Basically, strip the ends of the wires to be spliced.

Thead an appropriate sized adhesive heat shrink tubing over one of the wires.

Clip the end off of the terminal to form a barrel.

Thread the barrel over the same wire.

Twist the wires ends together end to end.

Coat the twisted wires with gray anti oxidation compound available in the electrical department of any hardware store.

Move the barrel connector over the exposed twisted wires and crimp securely.

Place the heat shrink tubing over the connection and heat.

 

"Butt connectors" aren't what the Toyota-spec connectors are. The Toyota ones make parallel splices, not butt splices.

If you were going to cut up a terminal and use its barrel to make a parallel splice, I guess you could also cut a common butt connector in half and use its halves to make two parallel splices.

The thing is, most of those ring or spade terminal barrels that I've seen are the open kind, metal that's stamped so its ends curl around and meet to make a barrel shape, but the ends are just next to each other. I think (though I haven't looked at one in a while) that the favored parallel crimp sleeves are unbroken tubular barrels.

And you'd have to improvise on selecting the size of connector, because you'd be asking the barrel sized for one wire to go around two wires and end up making a proper crimp.
