1985 Boost Signal Wiring

[DSPTurtle]

I have the 1978 wiring diagrams. The wire coming off my boost signal sensor is brown & white. It does not seem to go through the 14 pin at the rear of the engine compartment. Does anyone know how and where this little bastage gets to the cockpit? I can't find continuity anywhere. Any help is greatly appreciated!!!
Oh yeah, this is a 1985 factory slope. I took a bunch of parts off of her for my other project and now I am reinstalling and the only thing not working is my LED boost gauge. It is just flashing... apparently because it is not getting a pressure signal from anywhere.
If I go VFR direct, with a separate wire, from the boost sensor to the gauge, everything works fine. I have a missing connection somewhere from the engine to the cockpit and I can't figure out where.
Thanks in advance.

It is, in fact, pin 13 on the 14 pin connector in the engine compartment. If the wire separates from the socket inside of the connector, you will not get continuity to the cockpit. Hopefully this helps someone in the future...

Here was the required repair...



Which made none of this actually required...



All of this to make the gauge look like this with the key turned "on" instead of all the LEDs lit and the 1.0Bar light flashing like a stop light...



I hate electrical work!

Where did you get hold of this cauge? I really like it Where can i get one like this?
Is the wiring just from the boost signal sensor to the cauge? and add a power wire off course.



I almost bought this one at ebay but it was missing the backside of the cauge so i did not buy it
This cauge also have a digital clock it looks like. Perhaps it is some Gemballa stuff?

This is fake for sure. Strange enough with the hyphen, but if, then it has to be after the Lade and not before the Druck. So who ever this made was not German speaking like Gemballa...

That boost gauge I have was factory for the 930S. I have never seen another one. It was supposed to be like the 935 gauge that Porsche used until they realized the mechanical gauges were more accurate for race cars.
On another note, I put everything back together... making 1.0 Bar boost per the gauge (with my 1.0Bar spring). Got rid of my boost leak that was holding me back to about 0.5-0.6 Bar. Wow, it transformed the car. 20-120mph happens really freaking fast... even for a relatively stock 1985 930S
