Description of GM part no. 6289421 66/7 AC/ horn ground wire

[John M.]

6289421 - Can anyone give a description of this part number. It is a ground wire that is used on a 66 Corvette with A.C. to ground the passenger side horn when it is relocated for room near the condenser. It is shown on page 265 of my AIM, and is very hard to read on the copy I have. I would like to know the length and the color of this wire if that is possible. Must be a very obscure part as none of the searches thus far have turned up anything. Maybe you have one left over from a parts car or visible on an AC car with the nose off for repair. Thank you for any information provided!

John - check this thread in the forum - https://www.forums.ncrs.org/showthre...hlight=6289421

If you just enter the p/n in the Tech Forum search field you usually get a long list of post that contain a discussion about that part. In this case, only 3 posts but the 2nd one has a pic of the ground wire you are investigating. Good luck

Looks like 18 gage black wire about 12-15 inches long.

Thanks to both of you. The ground wire is exactly the part needed. It could have been fabricated but is pretty easily seen and having one with the correct ends crimped to the wire is great. After reading your posts last evening I spent a couple of hours reading Every page of the Zip catalog. and towards the back darned if there was not listed the steel re-enforcement for the horn relocation. Now that is an obscure part that I had no hope of ever finding and would have to fabricate. ( for those reading this in the future the part # is M3274) So all is well! Thanks for your help! I continue to be amazed at the collective knowledge that is provided on this forum .

Don't bother to look for NOS. GM #6289421 was never available from GM in SERVICE.
