Trailer Plug

pickle311 · 06-19-2013, 03:31 PM

I got the OEM hitch installed on my 2010 X5 and I'm having absolute hell trying to find the adapter I need for my boat trailer. The hitch came with the adapter to the 4 pin flat, but I need the 5 pin. I found one place online and ordered it, they called me stating it was out of stock. I called the dealer and they have no clue what I'm talking about.
Now I'm in a bind because I need it for this weekend to take my boat out.
Any ideas? At this point I don't mind paying for 2nd day shipping.

It converts 7 pin round to both 5 pin and 4 pin. Have one and it works great. Northern is also a great company to deal with.

I used the 4 pin supplied . It works great. I think the fifth is for electric brakes on the trailer which I don't have

The fifth pin is the solenoid lock out for those who have surge brakes on their trailer. The 7 pin connector is for electrical brakes on the trailer

Finally found one at a local trailer supply company, it was only $10. I didn't know it, but they told me the pin out on these are universal. If I had know that, i would have kept the one from my Tundra when I sold it. They have always been listed as vehicle specific, so I assumed the pin out was different on them.
