Sorry to ask a question that might or might not apply to a Corvette but I'm confused. I have a 93 Chevy truck with a 350 and am replacing spark plug wires. I can't tell which end is which.
The wires I'm replacing are aftermarket and are no help.
The ends are all 90 degree boots so that doesn't help.
One boot is a little thicker and is marked with an H.
I'm sure that the thicker boot with the H marking is meaningful but is it for the Hot end or for the cap where interference could be more of a problem?
OK. I found an answer that I used. Only one end had a dab of dielectric grease. That was not the H end. I assumed that the dielectric was for the spark plug end. Anyway, they are installed and the truck runs.
