I've done that with SOME wires FWF (I cut firesleeve and wrap it around the mount, and then plastic tubing around a small wire and then a tie wrap around that BUT these are small wires.
I treated the battery cable like nitro, because it's just not one I want anything but treated like a baby. Same with the alternator cable. So Adel clamps.
I know people don't like Adel clamps much but, if you make a little angle "standoff" rather than just putting two together, they're pretty easy.
I've tried all the various tricks and tools. But
this is the one that won my heart over.
