Could someone please provide the point to point instructions on how to connect a Hopkins #48895 converter to power my Harbor Freight Tag-along trailer lights?
My MotorTrike Razor has a 6 pin connector. I have purchased a 4 pin flat adapter which gives me, running lights and turn signals but no brake lights.
I was told that the Hopkins converter would take care of all the lights. I have tried to connect it to the 6 pin to 4 pin adapter but it only allows running lights and nothing else.
This is how I have tried to connect the Converter but I have less light functions with it than I did before I tried to connect it.

Re: Trailer wiring query
I'm not familiar with the 6 pin setup, but found this...

Re: Trailer wiring query
wingpilot08 I appreciate your attempt to help but it is the same as all the other diagrams. The 6pin on my trikes hitch and the 6 to 4 pin adapter provide running and turn signal only. It does not provide brake lights. I was told that the Hopkins Converter (# 48895) would provide the correct connections/lights. It has not. I am beginning to believe that the Hopkins Converter needs to be connected to the trikes under the seat points for ground/left & right turn/brake connections. The instructions for the converter do not address that theory however. I have asked on this and another forum if someone could provide an actual point to point connection diagram but have not (as yet) gotten a reply so I'm waiting hopefully for clarification.

Re: Trailer wiring query
So..just thinking this thru your diagram...coming from your trike 6 pin to the Hopkins, which has 5 input wires to 4 wires out to the trailer. You may have the hopkins converter reversed? The hopkins gets the signals from the brakes, running, ground and left/right TS and then converts to 4 pins. As I understand, the 6th pin just provides additional 12vdc for things like electric brakes and such.
BTW...love the black and yellow of your trike!

Re: Trailer wiring query
I am thinking the same thing, I think that the five wire end of the converter is connected to the trike while the four wire end of the converter goes to the trailer. If so I am rather surprised that no one seems to have picked up on that or managed to convey that to me. All I seem to be getting is that wire green goes to here, wire yellow goes to there, etc!.

Re: Trailer wiring query
Then try reversing the hopkins so the five wires connect to your 6 wire plug on the bike and the 4 wires from the converter goes to the trailer (trailer is 4 wire? correct?)alwrmcusn wrote: ↑Fri Jun 16, 2017 1:02 pm I am thinking the same thing, I think that the five wire end of the converter is connected to the trike while the four wire end of the converter goes to the trailer.

Re: Trailer wiring query
The 1800 has a 5 wire lighting system, so I would suggest going under the seat and connecting your converter to the appropriate wiring on the bike and leave the 6 pin set up in place if you ever have a reason to use it. If not, remove it entirely.

Re: Trailer wiring query
Final note on this subject:
I bought a Hopkins #48445 6 pin connector at Camping World for about $12. I then connected the wires from the Hopkins #48895 Converter to the appropriate inputs on the #48445 and connected the #48895 wires to the sidelights and taillights and voila!...everything works.
