The ICC switch can be used to flash the marker lights after passing and someone has alerted you it is safe to return to your lane. Flashing the lights is a way of saying thank-you. Flashing the four-way flashers also serves the same purpose and sometimes shows up better during bright sunlight. In evening or nighttime I usually use the ICC and sometimes use the four-ways during the day.
I installed an ICC switch switch in our motorhome and also used the same switch to flash the headlights since we did not have the "flash to pass" feature on the turn signal stalk like most automobiles.
When I push the momentary switch forward, it flashes the headlights off, if they were on, and on if they were off. Pushing the switch to the rear flashes the marker lights off if they were on, and on if they were off. In other words, the switch always turns the lights to the opposite state of what they were. Having the switch work this way means I push the same button whether day or night (if my lights were already on or off)
In the origonal thread,
ICC Switch Installation I used a toggle switch, but decided I wanted to use a rocker like the factory switches. I edited the origonal post to add in photo's of the new switch so you could see the design and the information would stay in one thread, but the switch is a brand called Contura. If you can't find one locally, you can order them online, just be sure to order both the switch mechanism, and the cap of your choice.
Two Bit,
You shouldn't have any problem putting the circuit into your truck as long as you can get to the marker light wire coming from your dash switch. Splicing the relay into that wiring per the schematic in the diagram will get you the feature you are looking for. If you don't want the headlight portion, you can omit the headlight relay and use a single pole momentary switch.
