The, soon to be released, Plug and Play Version includes a wire that can be used for activation of a relay. That wire takes the place of the red wire in the positive activation T-brake wiring with whichever activation (+ or -) your accessory happens to use.

Hello,
I recently bought LaunchMAX Trans Brake Kit – Plug and Play , and I want connect it with MSD 2-Step Launch Control. So I want to check connections.

should I cut the wire her and connect it to relay pin 85 ?
pin 86 to ground Clear
pin 30 to key on +12V power Clear

but
Relay pin 87 to the positive trigger connection for the accessory
do you mean I connect it for the wire that I cut?
And where I connect the wire from MSD ? it will be ACTIVATED W/12 VOLTS

Thanks and I’m waiting your help
