The reason that you are seeing continuity in all the pins on the trailer plug is that the signal is going through the bulb to the ground and back through the other lights to the pins. Almost no resistance through an incandescent bulb when not lit up. When power is put to a bulb it heats up and that is when you will get resistance.

I’m learning if I need it ,,,,great video

[@oysterjohn5669]

Thanks for a very informative journey.

[@chopchoppancake86]

Allways learn from all your videos !

[@richbutinski1367]

Great video... I believe the standard 7 pin plug is to match the 4 pin flat connector on most utility trailers with the use of the 7 to 4 adapter..

Great Info thank you.

Explaining electrical to a novice is not easy . Great job 👋👋maybe explain led bulbs to conventional and use trailer battery as source for plug confirmation on camper (isolate) vehicle from trailer.

It’s much better to back probe connectors than to “tap in” and puncture the wiring insulation which will cause possible corrosion issues later…..But we’ve all done it 🫣
