A while back, I found a couple different switches from the F-series trucks that have the extra pull-on switch for fog lights... They have the same plug as the van. Same circuit board too... just a few extra parts on it.
stock van switch on the left, new truck switch on the right with extra fog light feature.
Anyways... After a while it started to bug me that the LEDs inside of it are a different color than my dash lights.
So I pulled the switch apart to see if anything could be done. Sure enough, just some simple LEDs on a circuit board.
I hopped online to my favorite electronics site, found some green LEDs and today replaced the old with the new.
Now it's all better.
Now to wire in some fog lights, I just need a positive lead for the indicator light and a couple more wires for the relay. The crimp terminals for the connector are readily available on mouser.com.
