Problems Problems Problems lol
Okay, so my RV and Truck, like all vehicles used to be, are 3 wire 1157 dual bulb lighting systems (Left Turn & Stop,,,,,,Right Turn & Stop,,,,,Tail Lights). Similar I have three trailers all of which (like most trailers) are 3 wire so no problem so far.
HOWEVER my car/toad I haul or tow to Florida is a 4 wire (Left Turn,,,,,,,Right Turn,,,,,,,Stop Light,,,,,,,,,Tail Light). Sometimes I tow that car and sometimes I use it to tow my golf cart trailer. Its no big deal to buy a readily available cheap 4 to 3 Converter which I have installed on the car so I can tow my trailer which has the 3 wire systems and all works well as its already installed.
BUT THE PROBLEM is when I tow the car as a toad behind the 3 wire RV and it (car) has the 4 wire lights!!!!!!!!!!!!!!
So I go to Flea Bay and they have a 3 to 4 (some call them 2 to 3) converter which will supposedly allow my 3 wire RV to tow the 4 wire car yet all will work yayyyyyyyyyyyyyyy I hope???
QUESTION I just wonder if having BOTH those Converters (4 to 3 to tow trailer behind car, then another 3 to 4 so RV can tow car) will cause a wiring or cross talk or feedback rendering one or both inoperable?? I hope not since they are mostly just diodes inside those small plastic boxes. Sure, there are other ways to skin this cat (light bar on car trunk etc etc), but it would be neat and easy (once all is wired) if the 4 wire car will work behind the 3 wire RV and also,, if a 3 wire trailer will work behind the 4 wire car (but that's easy and already in and working)
Anyone used that 3 to 4 converter before?? Thoughts???
I figure there's no way to find out except to try it, so later next week I will let yall know what happens, cross your fingers.
