Default Battery Cable(Small Black Wire??)

I just bought this replacement battery cable and it is not like the original. What is the smaller black wire for? I know the big wire get's grounded to the frame near the crossmember, but the small one?????

some cars have a terminal block next to the bettery, it powers up stuff like the computer and the like. If your original doesn't have it, clip it off

I can't be sure but for one thing, the main cable looks entirely too small in diameter. The little wire is an auxiliary ground line. It's certainly not for an early C3.

Have a look at the battery cables for C3's in Lectric Limited's web site catalog. They sell duplicate original battery cables for Corvettes. See if the cable they sell looks like yours.

I bought a engine block to frame cable not too long ago from them. It was about aa long as the cable you pictured. $38 !!!! Copper has become very expensive lately.

Original cables were copper clad aluminum wire. Replacements if solid copper can be much smaller for the same cable useage.

Someone else asked the same question a couple weeks back. It must be some kind of "universal" cable they sell now. Neither of mine have it (71', 78')
Here's the link.
