Thanks John!

What does that 2-wire to 3-wire converter do when you've
got the brakes plus a turn signal on?

Are you going to sell kits ?? ;-)

Dave - It works just like in your car. The upper amber lights work as turn signals and, independently, the middle red lights work as brake lights. I don't know what is going on inside the Curt module but I hear clicking so relays (and diodes?) must be involved.

The only "problem" I have seen with this adapter is that when using emergency flashers both the red brake lights flash with a "hyper-flash" of the amber turn signal lights. Not a big deal. This may be caused by the Curt module or from using LED versus incandescent. Again, not a big deal.

But, no, I am not planning on selling kits. I haven't found a cheap US source for the 7-pin Euro connector! Anyone know of one?
