Completed: Low Fuel Light Mod

I had seen a light in my cluster that had a fuel pump with 3 drops of water next to it and I thought that would be a cool low fuel light instead of the Check Gauges Light coming on when im low on fuel. This is the light in the cluster Im talking about (credit ranger_key):

Here is how I did it:

First I took the cluster out, located that light and painted over the 3 drops with a brush and some flat black model paint.

Then I found the anti-slosh module: One of the circuit traces lights up the Check Gauges light when you get close to empty. Solder a wire to the trace shown in the pic.

The next pic shows where the light is. Ignore the piece of plastic there(i put that there when I was trying something else, you wont need it)Take the bulb holder out, solder the wire to one if the pins on the holder. I wrapped the wire around the pin and added some solder to hold it in place. I dont have a pic of that. Orientation is KEY when installing the bulb. The bottom of the socket is Negative, the top is Positive. You want to install the bulb with the wire on the negative side (towards the bottom).

Next pic is everything ready to be installed:


Hook the wiring harness into the cluster, but dont install the cluster. Turn on the key. Both the Check Gauges Light and the new Low Fuel light should come on.

Now there is a decision to make.When you are low on fuel, both the Check Gauges light and the new Low Fuel Light will light up. That circuit trace from the anti slosh module goes to the Check Gauges Light. I separated the connection from that circuit trace, but the result was that the Check Gauges Light stayed on and would not shut off. I check my gauges often, and for me personally that light is useless. So I removed the Check Gauges bulb, and put the bulb holder back in. If you leave everything as is, you will have both lights on when you are low on fuel.

Now I turn the key on, low fuel light comes on during the self check and we are good to go!

Thanks! For the clusters that dont have the gas tank on it, someone could take a junk cluster, cut that gas pump overlay out, and stick it somewhere else on the cluster, like where the door ajar light is. Cut out the door ajar overlay, and put the pump in its place. Just have to find that wire that triggers it, snip it, and connect the new wire to that.

I am sorry for bumping a crazy old thread (of which the poster has not been on in years) but I am wondering before I tackle this and have to find everything on my own (If I have to I will supply new pictures) does anyone know what traces and all are supposed to be used? (mostly wondering about the one from the anti-slosh module) I would rather not trace every lead from there until I find the right one)
