Thread: converting nato plug to 7 pin round

I sorted it out in light of day.

The plug that was on the trailer had been bastardised by someone (probably in the Army). All the pins had been removed and put back in from the opposite side hence the back to front labelling.

I cut off the plug, refitted the pins and rewired it.

Re the cable, the wires are in sequence 1 to 8 then black, then green/yellow (the latter is the same as the earth wire in mains wiring) for a total of 10 wires.

Because this plug was modded and another I had access to had the wires cut short, I had to go my own way with wire number allocation. It shouldn't matter as, at the other end, the terminal block has been dumped and the wiring extended by normal trailer wiring to the lights. That gets rid of possible poor connections.

The trailer now has LED lights. The convoy lights have been removed. It will be at the Expo on Sunday (sitting behind and matching Aust Frontline Machinery's 110).

Nato white wire five = reverse

Nato white wires six through nine were not used on this trailer.

Clarification.

Nato white wire five = convoy (white light at rear of trailer) but I have wired it as reverse

Here is my conversion chart with wire codes according to the yellow wiring tag on the terminal block of some No.5 trailers.
