Need help....some say changing 5-round plug-in on camp trailer to 4-flat plug cannot be done. Is this a true statement? Thanks in advance.

Hi Barbara,
It all depends what the wires go to. You might have a charging wire on a camp trailer for a battery on the trailer. If you don't, all you have to have is a RT, LT, Tail/clearance, ground.
If it does have a charge wire find out which one it is & don't use that wire. Like said above, if it is a standard wiring set-up, no problem , just use an adapter. They are cheap.
Ya might have to find a trailer supply to find one tho. NAPA might.
You can rewire both vehicle end and trailer end to any type of connector that suits your needs or get a adapter ...
WHITE wireAttach to the vehicle frame (Ground)
BROWN wireAttach to the running lights or parking lights
YELLOW wireAttach to the left-hand turn signal
GREEN wireAttach to the right-hand turn signal
RED wireAttach to the right-hand turn signal
BLACK wireAttach to the accessory terminal on the motorcycle

they are right you can change the 5 wire on the bike to a 4 wire very easy by just adding a converter . the problem is that your trailer is a 5 wire system and you can not run a 4 wire on the bike to a 5 wire trailer there is not enough wires to make it work . you need a #1 ground #2 taillight #3 brake light #4 left turn and # 5 right turn. if you make the bike to a 4 wire there are not enough wires for the trailer.
That's exactly what the installer is having issues with....attempting to change the round plug to a 4-wire flag plug (bike). We thought it'd be a easy fix!
Why in the world did they put a 4 wire flat plug on the trike? The harness I used on my 2010 Triglide was a 5 wire, they would have had to install a 5 to 4 adapter on the trike to get it down to 4 wires. This is the harness RIVCO Products, Inc.*::*Electrical & Lighting*::*Plug-In Trailering Wire Harness for FLH/FLT Harley-Davidsons, 1997 & Newer I used when I was pulling my Aluma MCT trailer with the Trigide I had, its 5 wire which the trike is also.
There is a way to fix this issue may have to change your plug end to do this..Not sure how the switch adapter is setup on your bike??
I had the 4-wire flag plug put on for pull-behind trailer, which was already wired for a flat plug. Bought the pop-up camp trailer which has the round plug. This is the one that has to be converted to 4-flat.
Most if not all trailer wiring is the same. It really isnt that hard if you follow the color codes on the wire harness. This goes the same for the Bike to trailer harness.
I have seen some nice hack jobs on harnesses that need to be corrected. A meter or test light does help if needed.

most wire harnesses should have a industry standard color and should be really easy to follow. But yes to be on the safe side a volt meter/light will help.Most of of the 5 wire trailers for bikes are L Turn, R Turn, Brake, Running & Ground. If you have an accessory it normally is a 6 wire system such as Bushtech, they have a 6 wire on the trailer and on their bike to trailer harness they jump the running light and accessory together at the plug. A lot of the 4 wire trailers will combine the brake and turn signals together, without a wiring diagram she'll have to get someone with a test light and multi meter to figure it all out.
