I too agree with using an isolator to keep wiring separate although some say it's not necessary. For me it's just piece of mind. I also use a 5-4 converter to match the bike side 5 wire to my cargo trailer 4 flat. I originally tried the Addon 5-4 converter and had nothing but problems with it. I ended up going with a Hopkins 48895 and it works great. There is no issue with brightness and everything lights up as it should. One thing to mention is that my cargo trailer is all LED lighting and I chose the Hopkins because it specifically works with LED lights but is also incandescent compatible. One thing I did to though was shorten the wiring between the converter and the 4 flat output as it was just way too long to hide.
