that's close to the original accessory TF fuse block, labels are all the instruction you should need with a factory harness and factory wiring diagram ... the fuse block was only originally installed if there were accessories installed like the labels call out, and the small wiring sections for each accessory were separate from the main harness, just the wires needed to reach each item from the clip on tab terminals .... the 3 wires you have on there are all to supply power to the block

the red wire should go to the light switch BATT terminal, that's for 'always on' power .... the gray wire goes to the PL terminal of the light sw to supply power when the dash [panel] lights are on for things like the glove box light .... the pink wire goes to the ACC terminal on the ignition sw, gets power only when the key is on

note that the ACC LP position [gray] doesn't involve a fuse, the panel lamp fuse is the small one on the light switch so that terminal just acts as a junction point
some fuse values:
backup - 9a
heater - 9a
fog - 14a
park brake alarm - 9a
radio - 7.5a
spot lp - 9a
under hood lp - 9a
