so im trying to install a blinker kit (led panels that light up with your turn signals and brake light) and you have to splice/tap into the wires obviously, to make it work. I have quick taps, I just dont know the layout of the tail lights wires. Any way I am able to "test" the wires without like cutting them, or is there some sort of diagram for the wires.

*im running diode dynamics tail as turn, on a '12 journey sedan*

 

I thought the Diode Dynamics module was "plug-and-play?

Either way, section EXL (Exterior Lighting) of the factory manual will have everything you need:

 

it is, im working on another add-on which are LED panels that go in your back windshield that correlate to braking/turning

 

 

For anyone looking..The wire colors for harness B60 left rear combination lamp are as follows:
Terminal 1- GRN Brake Light
Terminal 2- Red Parking Light
Terminal 3-Black Ground
Terminal 4 - Light Green, Turn Signal
Terminal 5-Grey trunk lid switch
Terminal 6- brown reverse lights

Hope this helps
