That looks like one of my conversions. The RC6J plug is a resistor plug. You will not need to shield the plug wire. Go to my forum on my website www.bcmaengines.com under my forums. I have a discussion there on avoiding interference. As for mounting this engine, It is designed for any rail type mount. The Hanger 9 Aluminum rail mounts are a good choice for this engine and I highly recommend them. Also Great Planes Giant Scale Adjustible Nylon Engine mount is also a good choice.
