I need a part number....

[GIBSON]

I'm restoring the wiring harness on my 73 911S. After it comes through the tunnel it makes a turn up the transmission area near the starter and goes through the firewall into the engine compartment. There is a rubber protective sheath that wraps around the harness in the transmission tunnel. Mine was so dried out it crumbled when I removed it. Does anyone know the part number for this protective wrapping? I suppose it's there to keep the harness from the elements, I'd like to replace it rather than leaving it exposed. Thanks

You might try a bicycle tire tube. Worked for me.

[GIBSON]

Tim, good idea. Looks like the same thickness, more or less.
There's this neighbor's kid terrozing my street, I could slow him down and solve my harness problem with one fell swoop...
Damn this board is good.

Bruce, When I get home I'll see if I can find a part number in the 72-73 catalog. This sleeve or bushing may be integral to the harness and only available by buying the wiring harness piece. It may also be listed in the body section. Another alternative is to get a piece of shrink tubing to slip over the harness and shrink it with a hot air gun; this makes for a fairly neat, and water proof covering. Jim

Jim, good idea on the shrink tubing but my sources don't include one big enough. It has to slip over the various connectors on the other end and then shrink down tight enough. I've looked in my 72/73 parts book but can't find the number, I'm probably not looking in the right place. If you see it that would be great.

it's part of the loom and would not have a seperate number.

Hi Bruce!
You can also buy Heat Shrink Tape (from a good electrical supply house). I've used this stuff in repairing all kinds of wiring harnesses. You can make a neat, professional-looking job with it if you're careful.

Bruce, Look in Volume 2 of the 72-73 factory illustrated parts catalog (911 Modell 1972/73 Gr. 8-N) in section 9 on page 1 right after plate 9/2/1. There is a listing for a rubber bushing (Porsche PN 999.702.044.50) right after the listing for the "Cables in Tunnel". This part no. isn't keyed to the figure showing the cables but its location in the listing, its universal listing (all models use it) and the quantity (1 per car) cause me to suspect it is your "sleeve". Also the 1974 models list the same bushing and PN after the main "Cables in Tunnels" listing. This part, if available likely isn't too costly so you may want to just risk ordering it. John Walker may be right though and it may just come as part of the entire wiring harness section. I wanted to replace a bunch of the rotted rubber bits and wiring on my son's '73T engine wiring harnesses and the only way I could see to get the bits was to order two new engine wiring harness sections. The new ones look exactly like the originals down to the smallest detail; it looked like the same person assembled the original and the replacement 28 years later. Cheers, Jim

Thanks for all the input, I think I'll price the part number and see what happens. If it's not outragous I'll try it. Got to try the shrink wrap tape as well, I've just used the tubing before.
John is probably right as usual but it can't hurt to check. I'll let you know what I find out.

[GIBSON]

After an exhaustive part number search, I have decided the wrap for the harness must be part of the harness itself and not available separately as John thought. So, plan B. I found some shrink wrap in a large enough size to feed it over the engine end of the harness and slide it into place. I left a hole for the starter harness to exit the wrap. Seems to do the job. I had to go to an electrical supply place to find shrink wrap that large.
Here's what it looks like:

Looks good! I did something similar when I installed a CD player in my '76 and wanted to collect the wires into a neat harness. I used four different sizes of shrink tubing; the largest being about 1.5 inches in diameter. Cheers, Jim

Looks like there's a serpent loose in your car, Bruce. Better go and find a mongoose

Good job dude! I still want to see this car. Hoping for remainder of parts next week. Glad to see you know how to relax!
