Need wiring help

[StoneColdBlue22]

Hi all,
I recently purchased a prosport gauge and need a source of constant 12v, accessory 12v, and a 12v headlight lead for the dimming function.
Ill start a thread once i get around to installing it incase anyone wants to do something similar.

I believe I lifted this from a dash cam install thread here. I followed it for my install (although I conserved the original fuses and used very low amperage fuses to feed the camera). Not sure where you’ll find the dimmed light power.

progress is slow but steady, havent had much time to really dedicate to the ST these past days, i have the vacuum line run, the pressure transducer mounted, just trying to pass the wiring through the firewall.

i temporarily ran the line inside the cabin and attached the gauge to a 9v battery as shown, only problem is.... as full load im only getting 12 or so psi, not sure if thats normal.
