$2 DRL solution for fog lights

Hi guys,
This is my first message, I wanted to thank the initiator of this Post "utkinpol" great find for this simple modification before presenting my frog.
For my part, I did it on March 8 and no signs of weakness with my battery or my CTEK maintains load.

Nothing like a badly presented frog!!!

Same Fog Light Hack for Cayman S?
Utkinpol:
When installing the foglight hack in a 2006 Cayman S, do I assume correctly that the wiring scheme for lighting is the same? My light switch looks the same, with the same settings as on a 997/1. (Cayman Gen.I don't have LED driving lights.)
My other question: Did you disconnect the battery during installation? Or will it suffice to keep the keys out of the ignition and the light switch in "off" during installation?
Finally, I have Sport Chrono Plus (i.e. PCM user programming for DRLs).
Will the fog light hack work on cars with PCM?
Thanks in advance,
JM

You can also check to see if the Cayman light switch has the same part # as the 997.
As indicated in the above post I also have the Sports Chrono Plus & have the PCM set not to turn on the DRLs.
I did not disconnect my battery but I did wait for the inside lights to turn off via the self timer. This way you know the "Home" wire is no longer hot.

I don't have any aftermarket DRL's, just the factory unit with fog lights.
With that said, can I do the hack? I wasn't entirely sure if the drain battery issue is a symptom?
Right now, I have the DL turned on...so my front bumper and Bi-Xenon come on regardless where my light switch is.
If I do this hack, the front bumper lights come on in DL mode but not Bi-Xenon?
Thanks for your help!

Battery Drain after Hack
I am unclear how additional battery drain could occur because of the hack, if no additional energy users can be identified.
In the case of a light switch, the only users, and therefore drain that could be present, would be lights. If no lights remain on after the timer goes out (which can be visually confirmed) no additional drain should occur. If the hack created a new path between B+ and ground, the battery would not be depleted slowly, but a fuse would blow instantly or a wire would burn up.
It seems simple enough to avoid any additional drain from the "home" setting (stock or hacked will be the same) by switching the light switch off altogether when leaving the car.
There will always be battery drain in a locked, parked car, not only because of electro-chemical deterioration of the battery, but because of ever increasing multiple electrical operations programmed to stay on after the ignition switch is pulled and the car is locked.
Anyone with remaining doubts about additional creep currents from the hack can easily measure and compare stock and hacked battery drain on a parked car with an ampere meter (digital multimeter set to milli-amps, and connected in series with the (+) cable of the battery.)

Probably like some folks here, I'm just paranoid. Having owned numerous Porsches over the past 15 years, I've experienced more drained/dead batteries with P-cars than I care to remember.
