i had one question about hooking up a tach light, and led lights, so that when i turn my lights on, they both come on. i looked for the fuse and fuse number, i can't find anything. it's a 1995 f150 xlt, can anybody help me with this??

 

They should be clearly marked on the fuse panel cover. You don't have to connect at the panel though, you can splice off one of the bulb wires or headlight switch.

 

Yeah, they won't be switched at the fuse panel in the cab. If you pull from the back of the switch you won't even have to run it through the firewall.

There maybe an illumination circuit at the radio, too.

 

how do you take the switch out, and then just splice the wire to the light with the 2 wires going to the led and tach light?

 

I added some lights by splicing into the light for my ash tray was a very easy location to get power and is also dimmable with the other dash lights.
