Where to tap into turn signal wiring
 

I picked up a DRL-1 from Daniel Stern lighting..

From the instructions, it needs to tap into parking lights/blinkers...

Besides in the headlight bucket/behind the bumper - where can I get access to these wires to tap into them?

Has anybody installed this and have any good pictures? :)

Oh man, those instructions are gruesome. Not necessary in 911 relatively uncomplicated electrical systems.
It would be helpful if you would post the year of your P-car.

Profile says 86 Carrera 3.2.

Easiest location to interrupt the output as it appears you need to do for this device, would be at the fuse panel.
Signals are fuses 9 & 10, running lamps are fuses 3 & 4.
Counting back from the headlight end of the fuse panel. Ignore the markings on the fuse panels.
Bottom of fuses are output to the lamps for front lighting.

Interesting. I don’t see that on my iPhone.

Currently using my PC. When using smartphone version of board, I don't see people's profile either. Maybe lack of space.

Yeah, sorry about that... 86 Carrera Coupe..

Was hoping to find a nice long run of wiring somewhere easy to get to.. doesn't sound like that is going to happen :) fuse block might be best.....

About using the front turnsignal as a DRL, you may want to change the turnsignals to LEDs. The OEM bulb will burn 21W with the bright filament. Since it could be constantly on for hours, it may overheat the plastic housing. Both brake housings on my '71 914 are melted above the brakes lights from sitting on the brakes for a long period of time.
