ABS Harness Refurbishment experimenting
#16
I need to repair my right front harness as well. If you recall the bracket that holds the white connector snapped off, and the wires got pinched in the suspension and broke right at that connector. Roger was able to find me the proper bracket (I apparently have a Frankencar w/ the old bracket) and I have a used harness, but the part inside the engine bay is not very good. Can I cut off the broken wires on the harness in my car and splice with the good half from the used harness? Is there reason this wouldn't work?

1. Purchase new harness. This would be the most expensive way since they can be unto $250 each, and the new ones are very hard to find. I believe 928srus sells them
2. Buy a replacement used harness. I see several on eBay right now. Find one with a good looking connector.
3. Buy a harness for parts (e.g. good connector) and splice the wires as you suggest.
FYI 944's, 968, and 911's of this vintage used the same ABS harness connector. You can use them as part sources or replacement harness so long as they are about the same length or longer than the one you need. If you go this path, note that the rubber grommets won't line up; you will need replacements.

A while back I went with Door #2, but the engine bay connector is in worse shape than my existing harness....which is why I was wondering about Door #3.
Looks like fraggle has been through this door...very nice. Door #3 it is!

You could remedy this a couple different ways.

Hmmm...this would be great tech session for Frenzy next year. Or, a fun rebuild party. Everyone pulls one harness to rebuild and goes home ready to do the other three.

Frenzy fun
If someone does take this on as a tech session at the frenzy, I would be willing to lend my two harness for experimenting. So long as I get them back in one piece and functional.
I have two harnesses that have been stripped of rubber coating. One I have started dipping and the other is still un treated.
I live in Portland and won't be attending, but I can mail them down.

Update: ABS light came on this week, so I put the car on ramps and looked at the wires.
This time the passenger side harness wires had drooped right over the wheel end of the axle on those CV joints and were wearing away. AARRGGH! So it was time to install all of the grommets on the rear wires.
Grommets go in one way only, split them with an XActo knife, put liquid electrical tape on the wire (it was just the insulation rubbed, no wire damage) then start putting them in. Two around the CV joint, then one going up, then two on the car, then another one on the car, then do the other side. Burned through a lot of them, but the harness is now very properly supported and should never go out again.
Which is good, I like ABS. But man, zip ties won't work, you need to get these groovy grommets!

Roger's got reproduction ABS harness grommets, $28 a pop.

New idea on DYI repair
A few years later from the original post, I thought I would give an update on a different approach to a DYI repair of the crumbling rubber coating and grommets. A quick disclaimer. All the harnesses are still available new ranging in price from $100-$220 depending on the part. So you should definitively replace your old harness with a new one.
But if you want to repair your harness, check take a look below. I stripped off all the old rubber and grommets and re-sleeved the harness with oil/fire-resistant woven split wrap (3/16"). And then used some sections 1/4" fuel hose and s to mount into the OEM position in the hub and chassis. I have yet to secure it to the chassis yet, but I have test fit the harness clips into the exiting mounting holes.
