Hi All
The following photos are of the trailer electrical plug that was on the rear of my Pattern 12 C60L when I got it. As you can see from the pictures it was in pretty rough shape. I was wired into the main wiring harness of the truck so it is likely original. It has four contacts so I would a guess that they are:
1. Ground
2. Brake/Stop Light
3. Tail/Rear marker
4. Blackout tail
Another thing to note is as this truck originally 16 inch rims the tow hitch is mounted between the frame rails, while my Pat 13 C60S has 20 rims and the tow hitch is slung under the frame rails. You really notice when you hitch a trailer up to these trucks. The Pat 12 C60L which now has 20 inch rims my generator trailer is tilled up a lot, while on the Pat 13 C60S the same trailer is towed dead level.
I was really surprised this morning went out to look for this to take a picture and it was on the shelf it should have been in correct box marked old Pat 12 parts.
Cheers Phil
