Search for a NOS fog light switch . Early 911

[Rick Cabell]

To answer your question, you could search Porsche salvage yards till you find a car with that harness. Then remove it. The catch is that a 40 year old harness is going to be in rough condition. Kroon makes a very nice product, as original as I have ever seen. $200 might sound like a lot for that piece, but it took a fair amount of time to make it. Everything in this sport has become a lot more expensive in the last 5-10 years.

hi

This harness is sold almost 200 USD including delivery
Is there any "cheaper" way to create this harness ??

How about just making it yourself? do you have the connector? if so it's just a few feet of wire and some soldering/shrink wrap..
on my 65, there is no such connector, so the harness was easy to put together...

Assuming since you thought the NOS switches and aftermarket harness were too expensive that you bought a JC Whitney or aftermarket switch? Pretty sure the proper original switch has the same numbers that the wiring diagram indicates. Maybe post a pic of your switch.

The original switch has the proper numbers on the back, and a yellow lens ;-)

Maybe this post on the 912 forum can bring some light (ha!) http://www.912bbs.org/vb/showthread....l=1#post381091

With the exception of the headlight switch, most Porsche pull/push dashboard switches, i.e., fog light, driving light, auxiliary heater, rear window defogger, etc., were designed to be internally illuminated when activated. Unfortunately, over their lives some of these switches have lost this ability with the causes ranging from a simple burned out lamp or incorrect wiring to a missing lamp socket in the switch itself. Thankfully, help is at hand.

If the problem is a faulty lamp, Stoddard (and probably other vendors) offers part # 900-631-102-90, Dash Lamp Bulb, 12V 2W BA7S for $1.49. If the socket is missing, part # 644-741-901-01, Single Spade Bulb Holder, $7.20, is what is needed.

As mentioned in other posts, the dashboard pull/push switches are elementary in design with their terminals “1,” “2” and “3” being internally interconnected and terminal “K” being internally connected to a brass plate that makes contact with the Single Spade Bulb Holder. In order for the lamp to illuminate, it is necessary to fabricate a jumper wire to run between any one of the numbered terminals and the spade connection on the bulb holder. The remaining numbered terminals are used for positive input and output to and from the switch while terminal “K” is connected to ground. Since switches could not care less which way the electrons are streaming, if you are using such a switch to control the negative or ground side of a circuit through terminals “1,” “2” and “3,” terminal “K” must be connected to the positive side of that circuit for the lamp to illuminate.

Donzenac: Please post a picture of the instructions that came with the Kroon harness. I plan on ordering a harness from Kroon, if it suits my needs. Thanks!
