After finishing my PSE install I think I owe you guys a summary. Some of this has

been described in other threads before so I only wrote it to emphasize or confirm:

1. As some have written before the wiring of the relay is quite confusing until

you figure out that the pins named under section 2.4 of the TSB are those on the

SWITCH, not on the relay socket or carrier.

2. The relay carrier goes off and on much easier if you remove the bolt in the

upper left corner that holds the hinge. Who engineered this thing anyway?

3. As on all other cars the dim wire GR/BL/BR wire goes into slot 25 instead of 28.

Most of the time when I was was in doubt which bridge to us I was able to indentify a

wire of the same color coding which was already plugged in the bridge.

4.Terminal 15 - pin 2 is in fact three wires not two. Don't get confused. Funny that

the german TSB states the number of wires correctly.

5. I messed up big time when I tried to follow the instruction to "run the three

leads of the relay socket through any free slot in relay carrier 1, noting the

direction of installation of the relay socket". Plugging all the wires in after

inserting the cables from the FRONT of the relay left me with a relay socket on

the wrong side of the carrier. You have to know that the socket itself has to

be installed from the back of the carrier. Just wire the socket and then push

it in from behind and you'll be fine. Well, maybe it was just the language

barrier and completely my fault but sure cost me some time to get the jacks out again.

A very small screwdriver used for the screws in sunglasses hinges will help if

you don't have the special tool.

6. I did not remove any panels to route the wires to the engine bay except for

the sill cover around the trunk release levers. I did not remove the seat for this

but it sure comes in handy if you don't have a short allen wrench. Helps with the

relay carrier removal as well. Just tuck in the wires under the side panels and pull

SLIGHTLY to stretch them diagonally which keeps them there.

7. The exhaust removal took me quite a while. My car is built in 11/1998 and was driven

all year round. Was I expecting the WD40 to rebuild the bolts windings? An angle grinder

was used to remove the 6 bolts in 4 clamps.

Fortunately the 3 bolts holding each can where still in acceptable shape.

Had the rear bumper and the heat shields off for that removal. Don't scratch your bumper

like I did! Install was a breeze and I had no problems doing it alone using my knee

to keep it in position while fastening the bolts.

I did not reverse the bolts in the holders for easier futur removal because I felt it

would compromise safety if the nut ever comes off during driving.

8. Vacuum install was really easy compared to the other two sections mainly because

that was only adding stuff not removing any stubborn equipment. I tapped the vacuum

line at a very easy to reach location near the tank's position . (See photo in first link)

I really recommend this since it also keeps the line to the tank short.

The last screw I tightened was the clamp on the connection betweeen teflon hose

and tekalan hose. Well, I should have had the air filter housing removed for that

but there was no way I would let this screw screw me.

I hope I could reassure some of the statements that were already made on this topic

and also added some new aspects. If you have any questions feel free to ask as

long as my memories are fresh.

Here are the links I used:

Hello Toddel68,

I have been thinking about installing a PSE for some weeks now and I have been gathering all sorts of information via a number of Porsche forums. There's no denying that www.renntech.org offers the best information.

Within a few weeks I hope to start installing a PSE on my 996 C4 (November 1998). I have read that you also have a TSB in German on how to install a PSE. It would make the installation easier I think having both the English and the German version of the TSB, especially when having to do the electrical wiring.

So, could you do me a favour and, if possible that is, mail me a copy of the German version.

Thanks a lot,

jo996 (the Netherlands)
