I'm not sure if you have one of our dimmer switches or not. ( u didnt mention that) But if it's ours then there should be 5 wires.

1. Black - goes to the ground wire from LED
2. Black - goes to the ground on Chassy of roadster (make sure it's grounded good.
3. Blue - goes to your brake lamp wire (use a tap in connector)
4. Brown - goes to your running light/head light wire (use a tap in connector)
5. RED - goes to the red/or white wire on LED (positive wire)

This module allows you to adjust the illumination of your brake power and running light power independently. You can turn the 1st **** down and the second **** up, then your product will be set at a certain illumination while head lights are on and then when you apply pressure to your brakes it will produce a brighter illumination. (however bright you desire)

As for the length of wiring. We have ours installed in our console between the seats. There is a hole going through the back of console that we drilled out a bit (just enough for the wiring to fit through.) This makes a convenient place for you to adjust the product. Also, you may need to add a little wire to the ground to find a good spot. (it's different with all roadsters)

I really hope this helps.
