I think it is:

1-signal - White
2-ground - Brown
3-shield

i found this one...

Yes that can be done too.
You drill out the internal "Hex" that's used to install/remove the plug and then Tap it.
Then you need to grind the outer (round) plug into IIRC a 17mm so it can be reinstalled into the block.

Had a friend with a machine shop do it for me and it's installed in my 86.5 "onion" car, front most hole.

wired it up your way Alan. after talking to Sean. still waiting to find the block plugs anyway. so i can't test it out yet.

Rob Edwards

How many block plugs do you need, Jake? I should have 2 here somewhere from the motor that the Zombie ate...

Ducman82

just 2 Rob.... that would rock.

Rob Edwards

PM me your shipping address and I'll try and find them tonight.

I actually don't think the selection between 1/2 ground/signal matters since it is a piezoelectric effect and not inherently polarized. You would think Porsche would have just picked a configuration and stuck with it across years though...

Ooooh, already pimped fo' yo' ride....




Interesting- never noticed the manufacturer's stamp (ARCO) on these. Am seeing if I can Google this manufacturer:

That would be an epic waste of time and gas, will pop them in the mail in the AM.
