Hi Richard, I tried fuse 2 and it still won't power up pre crank which is weird as the dash power up once the key goes in. I've double double checked all the wiring to make sure I haven't done anything different to the drawings that came with the kit. I've got the correct drawings as well for the hsf4 3.1 which I have.
Here's a link to the photos of the controller and the gauge
Starting to lose my hair over this install lol.
