A quick question from a complete novice.

I recently purchased a small fishing boat (12 ft. aluminum) and
trailer from a private individual. The trailer, I think, is from a
"kit" and the seller installed the wiring and lights himself.
However, they are not working when hooked up to my Hyundai Santa Fe,
which came equipped with a tow package. It has a "universal" light
hook-up/plug.

I'm told the reason for this is that the Hyundai, like many other
vehicles, has separate lights/circuits for tail lights and turn signal
lights. Advice has varied -- "you need a splitter"; "you need to take
apart your Hyundai lights"; etc., etc.

This can't be the first time someone has tried to do this. It doesn't
seem that I must "take apart" the lights on my vehicle. There must be
an easier way.

Is there a certain kind of lighting/electrical kit sold to accomodate
this kind of vehicle? Any thoughts on this subject would be greatly
appreciated..................jmac
