These flashers are something like the proverbial 'black box', except that the Grote brand are blue.

The instructions - well let's say that they don't exist !!! The flashers are supplied in a tiny cardboard box just big enough to ship them.

Matt, the fact that I'm trying to eliminate excess "clap trap" says that relays aren't the way nor are there any extra sockets or space on my AAW module.

I find it discouraging that something so evidently simple as an electronic signal flasher has virtually no internet write up as far as how they really work. Then, the two prong version should be a direct plug in, and in the case of these, a separate ground to complete the circuit. Of course some of the foreign make and commercial vehicles use up to a 13(or more!) pin flasher.

If anyone has found a good write up, let me know - though at this time it's just for my information.
