For the trailer - Yellow left turn, Green right turn, Brown tail,
White ground, Red stop, Blue "AUX" - back-up or Electric Brakes or
Battery Charge.

There are a few ways to do it right: The best for most people is to
go get the self-powered converter box that you need to run a 30-amp
lead through the car to the battery.

Or you can add two Stop lamps to the trailer, wire them with a Red
wire, change the trailer to a 6-pin round connector with a dedicated
Stop light terminal, and leave everything else on the trailer alone.
Then you don't need any converters at all, and the trailer works
behind any car or truck made. If it's behind an American car you just
hook up the original 4 wires, the extra stoplights don't do anything.

If you are somewhat handy with electronics and your car has a lamp
failure module, you can buy four cheap cube relays, run a fused lead
to the battery for power, and make your own trailer light isolator.
Tap in BEFORE the LFM box for your relay coil signals, and put reverse
EMF diodes across the relay coils (if they aren't built in) so you
don't create voltage spikes.

The cheapie converter that just taps into the truck lights will work
for most applications - but your trailer lights will not be at full
brightness due to the forward voltage drop effect of the transistors
and diodes in the cheap converter. You lose between .7 and 2 Volts,
which will noticeably dim the lights and make them difficult to see in
bright sunlight.

On some cars with lamp failure sensor systems (usually the high end
cars) tapping in for trailer light power in the wrong place can blow
out the LFS box and knock all your car and trailer lights out. And
that box is very expensive to replace.

Read your owners manual and/or ask at the dealer before you do
anything. If there are special restrictions, you need to know it.
