I bought a used NX plate kit for my 04 gt, i have everything install but wiring. I have a few questions and i hope someone can get back to me soon so i can button this thing up.

The wiring i got from him has 3 relays, one for bottle heater, which i have wired up already and 2 others for the engine bay. One i know has to switch the solenoid on and i have a firm grasp of how that has to happen, but what is the second relay for? i cant figure it out.

Also he had the positive sides wired with add-a-circuits, like harness + fuses with pins so u can just plug into an existing fuse block socket. my problem is that theres 2, one with a7.5 and one with a 20 amp, my guess is 20 amp is for the bottle heater. the other issue is that there arent any empty sockets with pins to accept a new circuit. if anyone has done this exact install please tell me which fuse numbers in the fuse block u used. pictures woul help so much.
