Jack, you're absolutely right; blade #4 is hot and blade #1 is negative at tow vehicle. I also suspect that you're right that maybe hilo didn't wire these trailer like that. I think the previous owner re-wired it the way it is. The white wire on trailer blade does match the #4 blade on TV (I know it's wrong, but it seems to be working this way)...I don't like it either. I connected TV and there was no spark or smoke, yay!! and everything seems to be working. I think in the near future I will re-wire the trailer wiring harness to match the proper wiring like the schematic on hilo. Thank you again Jack, and everyone else for helping me with this confusing wire problem.
