I have read several posts about having lights on in rv in order to charge toad battery .My toad charges with the lights on or off.I use 7 wire to 6 pin connector to the toad from rv. The 2 extra pins ...

It took me twice to follow your modification but I like it. My only concern is with the size of the charging wire when in the "lights off mode". The current available could be a bit high for the wires IF the toad battery is low for some reason. The Invisibrake only taps about 2 Amps which is enough to keep things going.
I know this sounds strange but if you add an inline 12 volt bulb to the relay supply line you will have a safety factor built in. The bulb will shine if the battery is low and slowly dim out as the voltage gets higher. If the bulb is placed somewhere you can see it (mostly hidden of course) then you have a visual as well. I put a bulb between the battery banks on my last RV until I installed the trik-l-start. It worked for several months.
On Edit, you could fuse the relay source to match the wire capability or add a thermal breaker. If the fuse pops then you need to charge the toad battery via running or other charger.
