i have a nos launcher and it has a ground output trigger. i need it to activate a lnc-2000 but its a 12v . i know u can do this with a relay just need to know how

 

Plug your ground output to Pin 85, 12V constant to Pin 86, 12V constant to Pin 87, and your activation input wire to Pin 30. When Pins 85 & 86 see power and ground it will create a connection allowing the 12V to pass in through Pin 87 and out through Pin 30.

 

u the man ty
