How to clean wire harness?

[jkevinc]

Greetings,

I was doing a little investigating of my one-year new 1989, and found this wire harness with a good amount of corrosion. Although the footwell location may have invited this type of corrosion.Certainly, as I poke around, I figure I will find more harnesses in similar shape

Can anyone identify the harness based upon experience. I looked in the 87/89 parts "Katalog" and did not find any obvious matches.

I invite any recommendations on how to clean, or even replace if that makes practical sense.

Thanks,

John

Flush well using alcohol or contact cleaner with a toothbrush on both sides of each connector.

+1 for alcohol or contact cleaner, a but of sand paper on the pins as well as in the holes will clean them off if you so desire. If you are looking to replace the connector you have a few options.

1. You can try and hunt down a replacement connector
2. Weatherpack (Weather Pack Connectors | Weatherpack Connectors | Nylon Connectors) makes some good stuff that I have used in the past. You can get a mixed pack of them with the crimp tool for a decent price and they are always good to have around. If you do this you will have to replace the connector on both ends of the harness.
3. You can pull all the pins carefully out and clean them individually.

Regards
Dave

Thanks Dave and 86 911,

I was considering denatured alcohol since it seems to be a "go to" solvent in many cases.

Regarding the contact cleaner, I have been looking at Gaig Laboratories DeoxIT D100S-2 that supposedly cleans corrosion and adds a lubricant (and is safe for plastic). My only hesitation is using it on a low voltage harness as opposed to a single connector for fear of some type of conductivity across the segments--probably an unfounded concern since the product seems to be used often by the audiophile community.

If anyone has experience with DeoxIT D100S-2, I would love to hear.



Thanks for the link to the connector store. It certainly feed into my tendency to make like new--a tendency that I am trying to resist since the corrosion might not be all that bad. I just do not know how touchy these items are.

I have used spray electrical parts cleaner from my FLAPS in the past with good success. Looks like road salt from passenger's feet (?). Denatured alcohol should work as well. Don't use brake cleaner or acetone.

Caig makes DeOxIt - I use it - no idea if better than CRS, Wurth or other elec. cleaners

you want to pull the terminal out of the plastic block and inspect the wire braid near the terminals very very carefully
