before I write this, please understand my poor English because I'm not American.

I live in South korea.

I got 04 350z convertible and I bought a tail lights product by Depo.

When I try to install Depo tail lights.

I really confused.

Old one has 3 wires. Plus, Minus, and brake.

But New one, Depo lights has 4 wires, 2 red and 2 yellow !!

I don't know how to cut and connect to which wire.

Please advice me.

thanks.

It goes into the stock bulb harness. Try connecting it both ways to see which way allows all lights to function correctly.
