Custom Audio Harness

This harness allows you to connect AUX from the AUX output of the Nifty City Module. 

This replaces the old-fashioned output from the module, to your armrest inputs, and keeps the installation clean and behind the headunit/dash area.

Only purchase this, if you'd like to keep your installation clean and behind the dash.
This harness connects behind your headunit and has a female AUX input which takes the male AUX output, from the Nifty City Module. 

Dark Mode

This feature will allow us to program your module to Auto-Dim the factory screen when your headlights are switched on & off. 

If this is not selected, your screen will maintain the same brightness level and will need to be manually adjusted.

Upon completing your purchase, you will receive your Nifty City-Stamped Booklet or Manual at the checkout, which you can download instantly. You will also receive an email with that booklet or manual attached. Sometimes, our manuals or booklets, are inside the packages, please see specifics:
