I am trying to wire my guages back to factory after taking out all the wires that were tied into the guage wiring. The harness to the guages(multi function tac, voltage, temp and water pressure) contains a yellow(+12v key on), black (ground) and green (tac sender). The wires are tied in series but at some point the green for some reason ties to the blue(backlight) wire that leads to all the guages and not sure why?? The yellow lead is fused and I am not sure what amp fuse to use as one is not present(empty in-line fuse holder). The tac is tied to the anc/nav switch with some wires dangling. I would like to tie them to the switch but not sure how to wire the switch up.
If someone could provide with detail or wiring diagram on how to accomplish this I would greatly appreciate your help.
