Outer Limits 4x4 Board

hi there i want to put a tb45 into my gq and i need some help with wiring as i want to run dual fuel thanks

If thats the level of effort you are going to put into the question, here is my response.

Red goes to positive. Black to negative.

Wiring diagrams are usually a good place to start

Sorry not much help on the wiring here either but im curious........ Why 4.5?
