anybody using JMS LaunchMax transbrake? ...or made their own using relays?

[Cobrakid]

hey guys, 2015-16 only please.

I got the JMS kit, b/c it was $209, and looks nice etc., rather than chancing my
own build using relays wiring etc.

I am having trouble getting it to work.

I am convinced I have the correct wires tapped and going in the correct directions etc.
the "box" lights up like it is supposed to perfectly when I push momentary button, BUT
it is not doing anything?

any thoughts, advice anybody else have one of these?

Could be a number of issues. You should call up JMS and talk with their tech support.
