making marker lights flash
Ohk well i have way to much time on my hands today and i got an idea. Is there anyway that you could wire up the marker lights on the side of the truck to flash with the turn signals without having to do anything major. Like i said i just have to much time on my hands and just thought it would be somthing to do that everyone else hasent done yet, (as far as i know). So if you got any ideas let me know. Thanks in advance

You have thought of my idea when I rewire my truck. I don't think it would dim them that much for just adding another light to the wire. You would need to make sure your signal switch can handle 8 flashers.

that would be great! I have a buddy that's an electrical engineer. i was going to ask him what would be the easiest way to do it.

Check this thread...https://www.ford-trucks.com/forums/7...n-signals.html trying it out yet tho.
I posted this a while back with the same idea, haven't gotten around to

My Camaro does the same thing as the Jeep - alternating. Haven't looked yet to see how GM does it, but it would be really simple to just hook up relays, like the Bosche ones used for the headlight wiring conversion. That way you have no extra current load on the blinker circuit and no dimming problems.

Like what was mentioned in the other thread.
Hook the ground wire off the marker lamp to the turn signal wire, and it will blink with the turn signals with the parking lamps off, and alternate flash with the turn signals and with the parking lamps on.

You may have to use an electronic flasher, because this will change the load on your turn signal circuit which will change the current going through the flasher. This means they will blink too fast, too slow, or not at all. The flasher works by a heating element shorting and opening the turn signal circuit, and the lower the current flowing through it, the slower it heats up. The higher the current flowing through it, the faster it heats up. This is why these are referred to as "thermal" flashers. The change in current will depend on whether you wire the bulbs in series or in parallel (resistance will go up or down). Now, whether or not the current will change enough to cause a noticeable difference in blinking speed, you'll have to try it and see. My scenario is just a possibility. Make sure your fuses are at the proper rating, because if you wire them in parallel and draw more current, you don't want to fry the wire insulation in the event it happens to be too high.

The simplest way I can think of would be to tie a relay into the turn signal positive on each side and have the relay control the marker lights. Shouldn't be very much additional draw (as the signals won't power the marker lights) and it'll work properly - signal lights are on are on, markers are on; signal lights are flashing, markers are flashing.

ohk well heres what ive come up with. You can hook the back markers up by connecting the ground to the turnsignale wire only problem there is when you hit the brakes the markers go out. Now if you try to hook the fronts up they blink way to slow and blow fuses so that didnt work out so well. I do plan to look into to it a little more and mabey looking up a woganeer wireing diagram to see what i could come up with cause i would still like to make this work. Ill keep everyone posted on what i find

You can upgrade to a heavy duty flasher. The one used for trailer towing. That should eliminate the chance of the slow or fast blinking. And hooking them up that way would not put enough draw on the circut to worry about anything I would think. Otherwise how do people hook up trailer lights to their trucks?
