Has anyone activated the US model 968 to have the daytime running lights working? <img src="/forum/images/smilies/968/blink.gif" class="smilie" alt="" /> I believe this is standard on the Canadian version and entails an additional relay by the passager footwell. I'd like to activate for my car. <img src="/forum/images/smilies/968/unsure.gif" class="smilie" alt="" />

I haven't done it, but I recall others who have. All you need is relay G26, Part # 944 615 123 00. I hear it is pricy. If you want to adapt a standard realy for the task, here is the diagram. It is not a standard Bosch style pin layout so you have to use jumpers.

You Da man. <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" /> I'll give it a shot and see how bad the relay hurts the wallet. Thanks for your insight

If you want full time fog lights, get rid of the relay. That's what I did. I jumped it by running a wire with a fuse end from the fuse to the "power" inlet. Took about 5 mins and 5 dollars. Fogs come on with the ignition. I also covered my fogs with the yellow lamin x. Looks great, in total about 30 mins of work about about 35 dollars. A great mod to set the car apart from all other 968s.

Tell me more about how you did the wire and the Lamin x. Where do you buy it?

Me too, me too. Dealership wants $104 for the relay and none in the US. 1 in Canada and 13 in Germany.

if you have the relay part number, try calling your local parts store and having them look it up - don't tell them what car it's for



if you're stuck for a store, call clint and pacific coast imports in hermosa beach - he is really good at cross referencing parts like that

If you look at the wiring diagram above, you can put a jumper between pin 9 and pin 7 at the relay socket. The socket is in the drivers footwell, left side. Just listen for the door chime and the socket is right there. Note that if you do it this way with a jumper, The lights will be on all the time when the ignition is on.



The realy isn't that complicated but it has a funny pin configuration. Hard to imagine why it costs $100 <img src="/forum/images/smilies/968/mad.gif" class="smilie" alt="" /> .

Ok - You'r hot! <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" /> Electrical pun intended! IT WORKS GREAT!!! As I am getting old, my eyes had a hard time seeing any numbers on the socket so I had to rely on wire colors.



While I am comfortable with the 15A protection thru the fuse in position 35, I wonder why the engineers put in a Blocking Diode (BD) at the end of the circuit for Relay G26 Pin 8? Looking at the schematic, looks like power comes from M47(?) to Relay G26 Pin 6, to the actuator as well as a thru a tie point, across a transistor (?) to another tie point and down to the BD. What are they preventing from happening with the Light Control Unit (Relay G18) Pin 4 and Relay G26 Pin 6? <img src="/forum/images/smilies/968/blink.gif" class="smilie" alt="" />



Perhaps I shouldn't be too curious and again just say thanks for the insight. So...Thank you again!!! <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />

I have seen diodes across the coil leads to help prevent voltage spikes from the field collapse, but this is a bit different. There must be some kind of possibility of backfeeding voltage from somewhere. Not sure that the gizmo is across the leads. Oh well. It works!

Interesting... <img src="/forum/images/smilies/968/huh.gif" class="smilie" alt="" /> I checked for a voltage draw across the terminals (Pin 7 and 9) with the system jumped and ignition off. Nothing pulling. I am looking to get a job at the local Porsche dealership this coming week and the shop foreman has been a very good friend of mine for the last 10 years. Perhaps he can shead some light on the diode. If so, I'll pass on my findings.



Career changes stink but there just aren't allot of long term stabile positions in military aerospace. I think it's safe to say that the reason I like Porsches soo much is that they are built like aircraft. A bit finicky and they each have their own personality. :-)

oh oh, I think schwartz068 just defined why I like these cars so much.... and put up with the idiosyncricies and all the searching for stuff to keep them running well....

Been friends with the shop forman at the local dealership going on 10 years. We discussed the relay and the blocking diode. The BD is to prevent the realy from chattering (opening/closing) and eventually goes to ground. Your assesment about just jumpering the two terminals is perfect! His hat is off to you (as is mine). Thanks for saving me the $100 plus dollars. <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" /> <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" />



On a side note...looks like I'll have to wait a few more weeks for that potential job. I understand the 4 door Porsche is for real. I wonder how sales on that will go? <img src="/forum/images/smilies/968/dry.gif" class="smilie" alt="" /> The SUV is sure selling like hotcakes but with an 8 cylinder and gas as high as it is, I am glad I sold mine. <img src="/forum/images/smilies/968/rolleyes.gif" class="smilie" alt="" /> I know, I know...if I have to worry about gas, I can't afford it. <img src="/forum/images/smilies/968/ohmy.gif" class="smilie" alt="" />

now the unasked question - why do you want your lights on during the day?



in the past i've actually installed a brake light cutoff switch, and reversed the order of what comes on at the headlight switch (main beams first, then parking lights) to try to reduce my visibility to the local constabulatory - that's definitely going in the other direction

Too many young kids driving like idiots around here, causing accidents and killing each other off trying to be the Dukes of Hazard. The cops are cool but I'm old (47) and have a new family (see attached). Worth a thousand words eh? <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" />

lol - i actually launched one of those cars over some railroad tracks at 130 - not pretty - that stuff only works in the movies



not sure the daytime lights are going to help anything but sylvania's stock prices though



there are a couple of studies out there that actually show an increase in rear end collisions with cars with daytime running lights, on cars that also switched on the tail lights, because the difference in brightness between tail light and brake light is too small during the day in direct light to be able to tell that someone is on the brakes unitl it is too late



now if you could disconnect the tail lights from that circuit, so that only the front lights came on, you might then be on to something - then of course some yutz would drive around at night thinking his lights were on, and we would have a whole new problem



the real problem is that people just don't give driving the amount of concentration that it really needs - they are too busy talking on the cell phone, reading the paper, doing their makeup, and yelling at the kids to pay attention to the guy they are about to run into - i've been nailed 4 times in 2 years (twice while my car was parked) - i agree we need more visibility of our cars - hope this works for you - didn't even help me to have my horn blaring and my lights flashing when the minivan creamed me

Actually...the only lights illuminated are the front white beams. No other bulbs. Give er a jump and check it out. I think you'll like it and you can restore your wires back to OEM configuration.



Your right about the yutz though. Heres what you get if you jump the terminals:



White "Driving" lites illuminate with ign. sw. in run position. When cranking, lites extinguish and them re-illuminate after start. No other lites on.



Place rotory light switch to position 1, instr. cluster green Parking lights advisory illuminates as well as all exterior lights (less headlamps which stay off and resessed). Driving lights rocker switch has no affect. Pulling the passing lights lever (RH side of steering wheel) rearwards illuminates the brights in the fog lamp housing. Release the lever and passing lights exting. Rotate rotary light sw. to 2nd position brings up headlamps as normal.

it's illegal in california to run fog lights when no fog - also illegal to run fog or driving lights in town - both must be used in conjunction with main beams and not alone - people do it, and they may never get pulled over for it, but sure as heck, the moment i do it, i'll get yanked



i think these laws are to deal with the aformentioned yutz



glad it works the way you say though - that at least eliminated the invisible red light worry

We've had DRL's in Canada for over 10 years now so there are lots of statistics being compiled. Bottom line - they help to reduce accidents.



Effectiveness of Daytime Running Lights in Canada; H. Arora, D. Collard, G. Robbins, E.R. Welbourne and J.G. White; Proc. CMRSC-IX; pp. 29-38; Montréal, Québec; 28-31 mai 1995



Abstract: This research evaluates the effectiveness of legislating the mandatory installation of daytime running lights (DRL) in new Canadian vehicles. Statistical analysis focuses on the reduction of two-vehicle, opposing direction, daytime collisions for vehicle model years before and after the legislation (1989). The analysis showed that use of DRL reduced those collisions by 8.3%.



Detroit, Michigan - New findings by the National Highway Traffic Safety Administration show daytime running lamps significantly reduce certain kinds of daytime crashes. The recently released NHTSA study, which used federal crash data, shows that from 1995 to 2001:



DRLs reduced opposite-direction daytime fatal crashes by 5 percent

DRLs reduced opposite-direction/angle daytime nonfatal crashes by 5 percent

DRLs reduced non-motorist, pedestrian and cyclist daytime fatalities in single-vehicle crashes by 12 percent

DRLs reduced daytime opposite-direction fatal crashes of a passenger vehicle with a motorcycle by 23 percent.
