I found some pictures.

The 1st 2 are as it's been for 42 years. The 1st not very good shot shows it curving around the front of the head and exhaust manifold and what remains of the fabric loom (lower left of alternator pilley). The 2nd shows it along the valve cover (looks like there's only one clip just to the right of where the 2 wires cross and the wire is not actually in it in the pic). The clip is barely visible in the resized picture...sorry. I don't recall what the brown or black wire is. The third is a shot of the retainer clip at the water pump on the truck as it exists today.

The early Corvettes used clips that were attached under the top valve cover bolts. Perhaps that's what yours has. If you don't have the clip welded to the valve cover, you could order some of those used on the Vettes.
