I've well and truely done it now. I'm into my TB job, cleaning as I go, and I've hit a snag. This car is a study in deferred maint.

Anyway, there is a rectangular connector located directly behind the jumpstart lug, that is at the end of a long cable harness running from left to right across the front of the TB covers.

Upper right of the image(I hope). This connector shows frayed and shorted wires, that have been touching for a long, long time. The upper half of the connector is falling apart, and much of the phenolic is crumbly.

Can someone ID this connector by Porsche PN? I will have to strip back the wiring and get good connections, so I would like to start with a good connector. I can try ordering it from the big 3, but I'd like to know more of what I am speaking about first.

The rest of the job is going well, I have a new smog pump that's going in, and other new belts, as well as the WP, crank seal, idler wheel, and some other goodies. Believe it or not, if I see this right, the TB tension line is wired off!

Merci de advance....

Yeah, I was afraid my Sun system wouldn't grab the image file right. Anyway, it's the photo above step 31 in the upper right corner of:

Doc,
Did you mean upper left corner?

yes.

don't know the p/n but that's the main harness coming from the alternator and the plug connects it to the main harness going into the fuse panel. not a good one to have shorted.

Doc,
Just searched the PET.
Harness is as shaaark89 said Pt No 928 607 002 17
Plug Socket 911 612 497 00 may be what you need but could only be half the connector as well. PET is not very clear.

I figured that, due to the gauge of the wires, and the size of the pins. Thankfully, I undid the batt cable first, but the car runs fine, I have a fair number of warning messages on the dash. Maybe this fix will sort some of that out.

If I can't source a new conn, I'll make one up from a heavy molex. But that's a lot of work, and is non-orig. Given the poor quality of the wiring I've seen so far, I would be an upgrade.

There have been other posts on problems with that connector...many reports of the wires' insulation rotting away and causing BAD shorts.
WYAIT - Trim back the insulation several inches on the wire bundle and inspect closely!

If this is the same harness - Rennlist sponsor 928 motorsports makes their own replacement:

Doc,
Just looked at my car.
I think the plug socket as I stated above will be usefull - if you can get one.
I could fax or email you the diagram from PET if that helps.
Let me know.

Yep, that's the problem child. Luckily, Porsche here in town can get a repl plug for $37. Which I'll do right away. The harness replcement will come later.

Thanks to all for the quick help. Tonite I'll have the belts fully exposed. I'm working through inches of grim from a failed FMS. Someone mentioned a seal on the oil pump - housing - o ring - gasket? Can't recall, but I may need that.

Doc front main seal , oil pump seal, oil pump o-ring ,three oil pump bolt O rings, two camshaft seals , tensioner gasket , tens boot , tens 0-ring , oil dip stick seal 900 174 044 40, possibly oil pan gasket and cam cover gasket set . The world will be a much cleaner place. When you decide to do the intake manifold dive there is another bunch of hoses .The oil filler housing needs a gasket . The cooling system needs about 9 new hoses ,thermostat housing needs a new inner seal may as well put in a new heater valve and thermostat . And yes the front engine harness is becoming a big problem especially for the older cars (somehow we consider S-4 to be newer ) Carl has reproduced the discontinued very early harness.

Got the FMS, will try to source the pump seal, pump o-ring, pump bolt o-rings, and oil dipstick seal (thanks for the PN). The rest of the stuff will be for another day. This is what I can do while in the TB/WP area.

As long as there is good insulation back a-ways on that front harness, I can fix it. I may look into a slightly less costly Molex aternative to an entirely new, but OEM style harness setup. Although that is the correct way to go at this time, the original PN indicates a 911 stock crossover. Clearly, the connector is exceeding it's rated current capacity, and allowing too much resistance to build up. Replacing it with EXACTLY the same connector is not the best alternative. It will fail again, mit spitzen, shparken, und fusen apoppin.

Jim - You guys should make a few "WYAIT" kits...like the above. Price it out a little special! BIG added resource on your website!
Would be cool to develop a posting with many jobs listed that had a WYAIT kit and list! I know it can be gotten from going through all of the 'usual suspects' webpages (pirtle, jorj, etc. etc)...But I don't recall ever seeing a listing of them all in one place.

OK, I've got all the seals for the oil pump lined up from ZIMs. I concur about the DIY kit idea. Some customer will always want their own little thing added or deleted, but I would have preferred to call and say "TB/WP" and at least have a handy list of common items like the FMS, oil pump set, tensioner boot and o-ring.


Newbies rely on a vendor to guide them through the process a bit. Downside is if you make up a kit like this, customers might opt to going back and ordering individual piece parts, which is higher mark-up for the vendor. I read the Pirtle article carefully, and although there is a nice shopping list, none of the oil pump seals or FMS were listed.
