I purchased a electronic ignition from RCEXL for my zenoha g38 to relpace my magneto. My question is I was told byRCEXL that I have to cut a large hole in belly behind fire wall to insert the sparkplug cap thru so I can get it to the engine.I dont want to make a large hole like that.Is there a way I can take the cap off and insert the wire thru the fire wall?? Than insert the cap?Are all electronic ignition wires like this,To bad i couldnt unscrew the wire from the spark plug cap and run it thru the fire wall than hook cap back on allowing hole to be small thru firewall
