You're a wealth of knowledge - huh?
Looks like it can be used for electric brakes. I imagine (
) that could throw more than 10 amps when engaged. I also see where they have an Aux/ABS Power pin. Also a good sign. I have some homework to do and they're really good at answering questions.
Thanks for the tip (and link).
