Technical Support / Re: No power for brake lights at coach 7 pin connector
« Last post by Steve Huber on July 31, 2026, 12:14:04 AM »Richard,
Did some digging into the various docs that show the brake wiring circuit. Unfortunately we don't have a specific 07 Contessa set of diagrams. However the 08 Contessa should be wired the same way. We do also have the 07 Patriot diagrams which may help but the Patriot is a more complex coach so differences exist. That said...
The 07 Contessa brake lights are in the same bulb as the turn signals but have a separate filament so if you have the turn signal on and step on the brake, the turn signal should continue flashing while the brake light illuminates. Check that your coach does this. The wire that feeds the brake lights is labeled VGC4. Hopefully you can read it on the wiring in your coach. It is pin #5 in the tail light connector that plugs into the tail light assembly.
The diagrams also show the turn/brake light signal to the tow connector goes directly to the connector from the turn light switch with no fuses or relays in the path.
The 07 Patriot diagrams show the brake signal runs to the tow connector on a Blue wire in the 5 oclock position. Not sure if this is applicable to the Contessa.
I think your problem is due to a bad connection, not a fuse or relay. That said, if it were me, I would ID the pin(s) on the Toad that supply the Toad's braking system. That will then tell you what pin(s) on the coach tow connector supply the brake signal. Then trace the wire connected to that pin. It will either be broken or have a bad connection at it's junction(s) with another wire.
