Electrical Plug for Trailer? Help!

It>Link gives a good description of proper trailer wiring; there is actually a code for this type wiring.

If you put the emergency flashers on on the truck, you then have a pulsed power going to the brake light pin on the connector. Make sure you have a good gound to the truck from the trailer (usually can find this connector pin easy by looking behind the one on the truck to see the jumper wire to the frame or connector mounting bracket). Now, take one of the wires from the trailer cord and touch it to the brake pin on the truck side. Whatever this wire feeds will be flashing (if it's the brake wire, you should hear the magnets snap in and out on the drums). Tag each wire on the trailer cord when you know what it is. Then turn on one thing at a time on the truck and touch the corresponding wire to the pins till you find the one that has the power on it. Make a drawing as the other guy said and put on copy in the truck and one in the trailer so you have it for future use if needed. Doing it this way eliminates the need for a test light/volt meter and second power source if you don't have them handy.

Without knowing your wife Bob, you usually can't go wrong with flowers, a nice dinner out (not fast food) and jewelry. On the other hand you have those "one of the guys" women that would be overly happy with a new set of sockets or a cordless tool too. Got a female friend of mine, had her a custom gold necklace made for her Christmas of '97 that I don't think she wore twice since that day. Got her a 14.4 cordless Milwaukee drill for her B-day last June and she about has it wore out. All in thier tastes. he he Good luck (just stay away from things like irons and sweepers, tends to PO all of them real quick!)
