PSE for 986S


Recommended Posts

Um... for what model and year of car?

Ooops, sorry Loren.

01 986S. The problem as I see it is that the PSE "kit" for an 01 does not contain the switch or the switch wiring harness. The original install docy from Porsche doesn't list a switch or the harness, either, so I don't think they are missing.

Also, the relay is version "2". The terminals are different in the "3" (both activity and location) according to the wiring diagram for the switch so I don't see any way to use the "2". Of course I chickened out after I had the tuning pipe apart, the relay box out and everything...

I only know of one other person trying to retrofit this to a year that didn't have the switch available - and we are both lost. So, feel free to correct me if I am wrong, but it seems to me the best way to handle a retrofit is to ante up for the harness and a "3" relay to be wired as if the car was an 04 or later. Can anyone confirm or deny with any conviction?

The other thing is I can't figure out if the PSE, which I successfully installed minus the vacuum/electrical lines, is actually open or closed as a default. (The vac input to the flap actuators are capped) The tone is throatier, but not really much if any louder than it was. If this is "open" there is certainly no point in pursuing the switch any further, but I really expected more based on what I have read. Perhaps it is because my prior toy was a '92 Miata, S/C'd to 10lbs and a relatively free breathing exhaust (read: too loud!)...

Thanks for the help, it's kind of a pain being a newbie!

Any input to solve this dilemma would be fantastic. I am also in the same "jam" if you will ... I have the PSE system (pre-2002) and the switch right now, but no part # for and therefore no relay or harness, etc. If you could include the part #s for this installation, that would be fantastic. My car is a 2001 base model. Kevin, did you come across a pdf file for the switch diagram for the 986?

Also, can I get some clarity about this: "the relay is version "2". The terminals are different in the "3" (both activity and location) according to the wiring diagram for the switch so I don't see any way to use the "2"." Forgive me but I'm a bit confused. Is the "3" the relay for the post-2002 version?

Thanks in advance!

Josh, The relay and a harness should have been included with the exhaust install hardware (vac lines, nuts bolts, stuff like that.) That was all inlcuded with my exhaust. The relay part number ends in ".02". The wiring harness is only for the relay they supply, and since there was no switch in the first years there are no wires for it. I purchased the switch later.

Looking at the wiring diagram for the switch ( which is apparently included for later cars) the relay part number ends in ".03". The circuitry is clearly different than the 02 because the terminals are in different locations, and more terminals are used.

That is as far as I have gotten. I am hoping someone will chime in with an answer at some point. I had a friend that is an Electrical Engineer, but he has since moved and I have lost contact. He could have resolved this in a minute or two!

Hey ---

Looks like we're getting no luck here ... I gotta admit, I'm thinking of taking it to the dealership to have it installed. They have to be able to figure out a way to do it with a retrofit, right? I don't know if you saw my post on the other forum but long story short I was shipped the wrong PSE system ... new one will come in within a few weeks. What a PITA thus far ... I hope it's worth the wait and expense.
