Towed car lights & battery charger wiring.
I am sure I am not the first who wants to do this, yet I am struggling to find the correct parts.
My current set up:
1-) Back of the RV available 7 way female plug (OEM)
2-) 7 way to 4 way adapter (from Wall Mart)
3-) On the towed car portable/magnet lights are currently powered with straight 4 way attached back of the RV to the 7 way to 4 way adapter.
Desired new set up:
1-) In addition to be able to continue using the portable/magnet towed lights with its 4 way plug,
2-) Provide 12v power for towed vehicle battery charger. (Purchased RVi battery charger)
3-) I need some kind of a 5 or 6 way female plug (receiver) with 4 way also to install on my towed car (jeep) bumper where i can connect the 4 way portable/magnet lights connection and the battery charger 12v (this would be permanent) then get a 7 way to 5 or 6 way umbilical cord to connect from back of the RV to front of the Jeep. 7 way to 4 way adapter will no longer be needed.
What do I need to do this preferably without cutting or soldering wires. I am looking at Amazon and etrailer and I am perplexed.
Thank you,
AL
