Relay sockets and wiring guages
Just pulling together some additional features for my 911 as I get ready to pull the wiring back into the chassis now that it is all fully painted and such.
I have two major questions that searching this list and the web has baffled me on. First one is where do you get relay sockets? I found a great Hella relay that will work just great electrically to do a 4 or 5 wiper swipe after wash (p/n 5WG 002 450-111) and it specifies a type "I" pin arrangement....and that is the source of my question. What is a type I arrangement and where the heck do I get a socket to fit that? I might have one buried in my pile of wiring, but if I wanted to buy one, where do I get one ans how do I spec it? Is there a standard for relay sockets? Where can I find documentation and specifications? Secondly and more simply...what is the wiring gauge for normal wiring on a 911? What is that in US guages and any good sources for wiring of the proper sizes/colors? I have a few other places I will be rewire and put in additional functions that are sort of essential in Europe where my car will end up (remote lock/unlock) and LoJack type of tracking, so good sources of relay sockets and wiring is pretty important to me. Thanks in advance! Dennis |

Dennis, what year and model is your 911? The answer as to sockets will depend to some measure on the vintage. Porsche used to publish details and part numbers for sockets, connectors, and such. In more recent models, they've cut way back although the parts are generally available either from them or other sources such as Bosch. (I used the latter to source a replacement knock sensor connector for my '08 Cayman, unavailable in theory from Porsche. It also turns out that PCNA provides their dealer techs with a secret supply of replacement connectors, unavailable outside the dealership service dept. So much for "right to repair.")
Wiring diagrams will usually indicate metric wire gauge. You can Google for conversion tables between metric and AWG sizes, lots out there. There are many sources for good quality automotive wire, such as Prowire and Wurth. Where wiring diagrams don't indicate gauge, you can either measure the diameter of the wire you're replacing, or use guides such as Bosch's books that suggest standard currents and gauges for particular devices. Be sure you use wire that is appropriate for automotive applications.

I googled the relay you named and it has a photo of the contact arrangements on it.
It looks like it may accept the same connector as the 6 pin CDI and other relays in the rear fuse panel on the SC’s. 18 or 16 AWG is a comparable US wire size to most of the wiring used on the car for control circuits. I generally use 16 AWG as it is more robust. What color combinations do you need? I have most of the combinations used by Porsche made up for me, and can supply small quantities. (Most relay bases and connectors as well) PM or email me through the site if you want to.
