JMO413 Posted January 27, 2020 Share Posted January 27, 2020 After purchasing a hitch from Krustyballer I needed to add trailer wiring. My major hold up was I didn't want to cut into the factory wiring. So I started looking for preterminated connectors. I was able to find both sides available from ACDelco among others. PT454 is the male end. PT222 is the ACDelco number, I bought a S1056 from Standard. I bought both on eBay for $15 each. They have now both gone up to about $40 from what I can find. Then Minuit suggested Mouser Electronics. They have both connectors available in individual pieces. This is the page for the female connector. The page for the male connector. The page for the seals you will need for both connectors. If you want to make the harness you will need. 12048074 x 3 12052139 x 2 12059472 x 1 12052486 x 1 12052200 x 1 12052199 x 1 12045773 x 3 12052172 x 2 12048086 x 6 12048443 x 4 had to buy from eBay 12059168 x 4 That shopping list will build both connector ends. For my first one I started with the S1056 and added the Mouser parts to the other end. I then soldered in a 4 way connector. I wanted to be able to switch it the trailer connector ends if it gets mangled or corroded. I also plan on using this end that I will drill a hole in the bumper to mount. It should look like it belongs there. I then coated the solder joints in liquid electrical tape. This stuff works quite well. Wrapped the new harness in electrical tape.

JMO413 Posted January 27, 2020 Author Share Posted January 27, 2020 Added convoluted tubing and a tee for protection. One more wrap of black tape to keep the junk out. This is the junction the new harness goes between. Harness installed. Wired the trailer wiring to the other side of the 4 way connector. Harness to run from the new harness to the trailer wiring. With the additional connector in there the trailer end is easily replaceable. Taller wiring ran to the hitch for now. Bought this little tester for $7 and everything works! Here is a video of the testing. I have now made to if these and both work. I'm going to make one more beacuse I ordered plenty of parts from mouser. I know have trailer wiring and didn't cut the factory harness. If I ever run into problems with my lights I can just remove the harness and go back to stock if needed. The second one ended up much shorter. The last one I make I think will be even shorter. Link to comment Share on other sites More sharing options...

schardein Posted January 27, 2020 Share Posted January 27, 2020 Great write up. Here is a junkyard source for the connector: Link to comment Share on other sites More sharing options...
JMO413 Posted January 27, 2020 Author Share Posted January 27, 2020 Here is a description of what each wire does. Left to right top row of wired are for lights. Bottom row left is ground. By terminal is easier to use when all your wires are gray. A is blue in the truck and is for the taillight. Brown on trailer wiring. B is brown on the truck and RH turn signal. Green in the trailer wiring. C is gray with a tracer on the truck and LH turn signal. Yellow on the trailer wiring. E is black on the truck and ground. White on the trailer wiring. Second harness I made is much shorter. I like the fit better. This is why I added the extra four way connector. I already changed the trailer end to one that mounts in the bumper. Looks almost factory. I really like that it's out of the way. The best part is that it was $4 on Amazon! Ready to be used!! Link to comment Share on other sites More sharing options...

olddude Posted January 29, 2020 Share Posted January 29, 2020 2 different gauge wires, what are they? Link to comment Share on other sites More sharing options...

Not 100% sure the word were in the connectors when I got them. The larger matches some 12 gauge I had paving l laying around. The smaller wire is just a little bit smaller than the 16 gauge I have laying around so I would guess 18. Link to comment Share on other sites More sharing options...

Piece of cake, even for a old fart. I ordered all the parts from the shopping list from Mouser Elec. except the seals. Ordered seals from eBay. Had to get 50 of each, so if anyone needs seals I have plenty. Works great! Link to comment Share on other sites More sharing options...
