Front Sidemarker Flasher Module Options

[Spoke]

There has been some interest in a module that would flash the front sidemarker with the turnsignal. The rear running/brake/turnsignal board I did for the 356 using the front turnsignal bucket from a 914 uses the same function to flash the running or brake light when the turnsignal comes on.

The flashing circuit was lifted from the 356 board and placed on this board with some modification. The board will be about 1.6in x 1in and will be enclosed in a small plastic box. The module will replace the wires which go from the front trunk into the rubber wire channel to the sidemarker and turnsignal.

Basically the wires to the turnsignal and sidemarker will be pulled out of the rubber channel and connected to the module. The module will have wires that will be fished into the rubber channel and connected to the sidemarker and turnsignal just like the OEM wiring. The OEM wiring will remain intact keeping with my goal of no cutting/screwing/gluing plug-and-play installation.

@Spoke -- I love the idea, but have a question about the installation. Instead of installing two modules, one at each front corner, what about making a single module that goes under the dash and connects to the switch end(s) of the wiring harness? This seems like it would be a simpler install, since you wouldn't need to pull the wires out of the fenders and rubber conduits/boots, and you could control both sidemarker lights from one box. Basically, it would be putting the new controls at the other end of the wires, instead of at the light-bulb end.

I believe the sidemarkers are connected to the front running lights on each side with just a couple 12" (guess) wires, 12v and ground. To have them work independently from the front signals, you would need to disconnect the short 12v ones and run at least 1 wire from under the dash along the existing harness up to each side marker. So you are into the conduits/boots anyway.
In theory there would be less wiring modification since you 'should' be able to add the inputs to the control board right from the source switch as you say. The turn signal/flasher connection is actually quite easy; add spade lugs to fuses 5 and 6 and those are your left/right inputs. Running lights/emergency flasher is another matter. those wires come directly off the flasher. A bit of work to get to that and add a spade lug to the switch, then run that wire down to the control board.
Would require a 'dual' control board since flashing each sidemarker is an independent operation.
Both options would work, one isn't necessarily better/easier than the other. Just depends where you want to put your efforts.
