Trailer Light Connector - Brake Controller

[JourneytoRet]

Hi all.

My Clipper has what appears to be a factory-installed, 7-way connector. Does anyone know if this has a connector in the cabin under the dash? I have a trailer with electric brakes and a "new" (merry Christmas!) tekonsha primus iq brake controller and would like to connect the brake controller in the cabin if possible. The Brake Controller wiring consists of 4 wires: +12VDC (Black); Ground (White); Brake ON via Brake Switch (Red); and Tow Brake ON (Blue).

Merry Christmas AS owners!

I found a diagram in the manual that shows the wiring to the 7-pin round plug connector - but it doesn't appear to match any diagram on the internet. For example, via internet, the brake controller should go to a blue wire at the 5 o'clock position on the RV connector. But airstream's diagram doesn't show a brake connector. Anyone using the 7-pin with a brake controller have advice?

OK, after going blind looking at other posts, it appears the good 'ole "test and verify" rule comes into effect. I shall arm myself with a voltmeter, 12V power supply and an extra pair of hands. Parbly no point in posting anything more as it appears folks are just rewiring the plug to work with most "standard" 7-pin trailer connectors.
