Our Quality Taillights are Direct Replacement Units; the only wiring modification you may have to make is to wire in the Integrated Turn Signals. 

You will need to connect the Positive Lead from your Turn Signals only, the Negative Turn Signal Lead can be taped off and tucked away.  (The Taillight will get the Negative from the Taillight Negative)

You can pull out the pins from your Original wiring Plug and push ours in place and simply plug them into the existing connectors.  (They are easily removed if you have a small pin to push them out with)
As an alternative you can simply hard wire them into your Positive Turn Signal Leads.

The Blue Wire is for the Left Turn Signal
The Red Wire is for the Right Turn Signal
