Hey guys, what's the best way to wire up a dash light? Tie into the 'Bat' wire on the ignition switch (or the ammeter since it's less busy over there) or should I be tying into the taillight wire so it can only come on when the lights are on?

one wire to the ammeter and the ground if its a repop to the mounting screws

Connect it to the tail light circuit at the terminal block and put a fuse in series, some of the aftermarket dash lights are not reliable.

Put it on the live side of the ammeter if you want it to work with the key off.

Thanks guys, I ended up tying into the tail light wire at the terminal block. I figured I had no reason for the Dash light to be on if the other lights weren't on plus having it wired in any way that was always hot made me nervous.

Brad,
What size fuse?

Hi Charlie: Any fuse between 2 amps and 10 amps will be good enough to protect against a short circuit at the lamps switch. A members car had this problem and without a fuse it burned part of the wiring under the dash before we could break off the hot wire. It is fortunate that it happened when someone was close to the car and noticed the smoke. Brad.

I'll keep the fuse in mind for when I rebuild this switch, probably in the spring.

I can't believe some of you guys, wanting to complicate such a simple item! Dash lights didn't come with or need a fuse.

Any electrical circuit should be fuse protected to prevent a short circuit from burning up the wiring and possible causing a fire. Brad.
