It's a "ghetto" temporary install. Just a small bulb on the floor. I hooked it up to the fan relay.

The best/easiest way to do it would be to get a second set of radiator fan plugs from a junk car and make a short harness that would plug in between the car's wiring harness and the fan. You can then splice into the short harness for the fan light without cutting up any of your car's wiring. Or you can just splice directly into the fan wires. Use waterproof connectors to avoid corrosion. You really only need to run one wire from the fan to the light if you figure out which one is switched. But it's a lot easier to just run two wires from both fan wires to your light. Almost any wire will do. Something already paired together would be nice. Speaker wire or an old extension/power cord is fine. Just route it so that it won't get caught in any moving parts or pinched, cut, etc. Use cable ties or electrical tape to keep the wires from moving around. And when you route the wire through the firewall, make sure you protect the wire from the sharp metal edges of the firewall. You might get lucky and be able to squeeze the wires into an existing wiring grommet. If not, drill a hole after carefully checking both sides of the firewall for any important parts you don't want to drill holes into. Then install a rubber grommet to protect your wires.

A small 12 volt bulb like what's used in dash lights or parking lights will work. But be careful where you put it, they can get hot and melt plastic or carpet if they're touching it. Or you can use an LED. Most LEDs are not designed for 12 volt use, so they will need a resistor. I think something like 330 ohms or slightly higher will work. Or you can look for an LED that's prewired for 12 volt use.

I found the fan relay. Then just removed the relay put a small 18 guage wire in the socked and then plugged the relay back in. So now relay is holding the wire. Couldn't find a cheap LED at PEPboys so bought a switch with an LED light. So now light comes on when fan is on and switch doesn't do anything.

just about anything electronic has leds in it today, and usually they survive when the thing there in is junked for whatever reason. leds do need a resistor in series with them or they'll burn trough, but chances are you can find those too along with your donor led (560 ohm should be ok for 12V) perhaps someone you know has an old computer they're putting out with the trash (the keyboard usually has a few leds as might the power switch)

I changed it to this grill block:

I left the top of the grill open, but it wasn't enough air. So I ended up cutting out one side a little more. Now the fan only comes on at low speeds in hot weather, which it also does with no grill block. It's made from some kind of thick tar-like sheet. Not ideal, but it's flexible and I had it already.
