If specified at 50 ohms per foot the 400 scale should test up to 8 feet, and I assume ypur longest spark plug wire is 4 feet.
The lower the ohms the better the wire imo. I found out that I could use a carbon core distributor wire and solid core spark plug wires and not have any static on my radio or even people's TV's etc. Don't know if an MSD system would work with that but the wires I was using with points and factory performance ECM's had 0 ohms per foot!! Just had to have that carbon core coil wire on a street rig. The plug wires would last years but replaced the coil wire once a year.
Start on the 4M scale (4 Megaohms), and move down until you go off-scale, then go back one space.Hello I know nothing about these meters and I'm attempting to build my spark plug wires which they are MSD super conductors 8.5. Which setting do I use to get the correct reading.

As long as there is no voltage present you cannot do any harm that way.
Do yourself a favour, and measure the meter lead resistance first, and deduct from the readings to give the final result.
Exactly.Just my opinion of course.
