Help with Trailer Wiring

[Overlord66]

I just purchased a M416 and from what I can see in the pictures the wiring is original and has the giant military plug. A while back I came across this picture ( I think it was here) of a trailer that someone converted the wiring over to a standard 7 way disconnecting plug. I can't for the life of me find the thread or find the parts that were used. Any ideas where I can find the coiled 7 way to 7 way cable?

I think Northern tool has these? I have no idea what the military one looks like but I know I have seen the civilian coiled set at Northern.

Those coiled plug to plug connectors are used on OTR trucks. Any truck parts supplier should have them. Or, you can make one up, but finding the coiled wire might be a trick. I don't bother with the coiled wire in building connectors for the Cheap Utility Trailer. I just use normal plugs with straight trailer wire.
