7 wire circuit. Need to know where to connect each one of the wires . The one not used is the blue. I figured out the white wire. But the rest I don't know. Can I just cut and splice the wires at the tail lights?
Trailer hitch wiring diagram. Need help

What kind of car are you wanting to install this on? Year, make, and model please.
As far as can you just splice at the taillights, how many lights and what kind of lights are on the trailer? There is a huge difference in load between a trailer with 2 led taillamps and a trailer with 2 incadescent lamps and a full set of sidemarkers.

I don't own a trailer. If I need a trailer I'll rent a small one. Here in Sweden they come with 2 tallights (no led) and 1 sidemarker on each side.

It depends on your country laws and the trailer setups. There are basically THREE separate types of trailer (and vehicle) systems
1 Is the type on your mopar. You have the stop and signal with one filament, in which the signal switch disconnects the brake light power from the bulb that is acting as signal
2 you have SEPARATE brake lights and signal lights in which the signal lamp lenses are AMBER
3 You have SEPARATE brake and signal lights in which the lenses are RED
If common trailers "over there" have signal lamps with red lenses, you are all set.
Just hook your tail lamp line from your car to the tail lamps on the trailer
Hook up a ground
Hook up the left and right signal wires from your car to the trailer.
In this case, it won't matter if the trailer has separate brake and signal lamps IF THE LAMPS are all red
The last possibility is that your country REQUIRES stop lamps to be red instead of amber. If the trailer has separate brake and signal lamps but the signal lamps have amber lenses, then you can NOT use them for stop lights if that is the law there.
In this case, here in the states, manufacturers such as Valley make "converter boxes" which have solid state circuits in them, and which allow the intermix of these two types of systems. Their most common use (over here) is to take a car with separate brake and signal lamps and convert to "integrated" stop/ turn lamps such as your car has now.
It appears that Valley converters are only for what they are calling 3 way to 2 way, the last I described:

Another thing you might consider is rigging up a set of temporary either magnetic lamps, or lamps which you can easily screw to the trailer, IE mounted on a strip of lumber, etc.
