It fell off on pg 2, but I was going to ask Mike Hofer (redline) how he wired his lights.

He doesn't show an email, so I'll ask here.

How does one go about making an adapter or whatever so you can operate gooseneck trailer (5th whl) from a conventional semi-tractor? Most of the goosenecks have combination brake/turn vs separates for the semi-trailers...right? Also, how do you get a brake light to the gooseneck? We also wire our goosenecks & bumper hitch trailers using a semi-type 7 pin, but we use a wiring pattern similar to those of farm equipment. Except, we use the "1-o'clock" position for elec brakes & the center pin for +12V.

So, how is the turn/brake problem solved?

Here's our 7pin wire diagram for our trailers/goosenecks, obviously not for the semi-tractors however.

Thanks
