[ercoupe-tech] Ignition lead routing

[robertbartunek]

Noticed the other day that the lead wire to the top plug on the forward 
cylinder, left side (don't know if that's 1,2,3 or 4) is routed up and 
over the cowling brace, or could say threaded, then goes back to the 
magneto.  Looks like the wire is chafing at the point it goes through 
that small opening between the brace and the cowl.  Is this the normal 
way to route the wire?  If so, how do you prevent chafing?
