Anyone have an old UNDER HOOD MAIN HARNESS that they could clip the yellow fusible link out of for me?

Much appreciated....

I can flex the wire to the side and see down into the connection and see the wire strands, so I'd like to clean any corrosion that may have started down inside the connection joint. Is there a solution (vinegar??) that I can soak the wire in for a bit to neutralize the corrosion before resealing the potting to the wire??

Yeah, some water, a few seconds under the heat gun to dry and then apply the sealer. So the vinegar would dissolve any corrosion that may have formed within the strands?

THANKS

Be careful with corrosion inside of wiring, it's bad and can grow under the insulation. I have had issues with two Lincolns that didn't get driven much. The OEM power cable in one was ruined due to corrosion inside, the other was a custom made cable that I thought was done properly.

But it also had the same issue, which got underneath the large heat shrink sleeves that were put on. Tearing open the insulation exposed it, and it was deep inside several inches from the ends. Both of those were low mileage, the OEM was 110k miles, the other cable was a year old since made.

I don't know the likelihood of corrosion growing inside a small gauge wire like yours, it should be very minimal. Battery cables are really the only ones to worry about like that. If the wiring looked fairly good when you first exposed it, I'd use it, seal it as you are planning to of course. That's for OEM appearance and function too, I'd replace all fusible links with proper fusing if possible.

As others have stated , unseen corrosion, and just the affects of 50 years of continuous exposure and service would dictate a new one. They are readily available. Why burn your car to the ground using old, used wiring !?!?!
