Our F.A.S.T harnesses are just that a Factory Audio Signal Tap ! An economic version of our Original Elite system counterfeited by PAC audio /Stinger(LPH harness line). We created this audio harness line for those that want to build their own harness or repair someone else's "handy work". The F.A.S.T audio harnesses system is an inexpensive way to better your install craft and keep that vehicle resale value up.  It is compatible with our Elite Harness System as well. 

The Factory Audio Signal Tap harness comes with 3 parts.

• The Base connector: that will connect between the factory audio source like a radio or amplifier.
• The Speaker Accessory: that has the 4-channel speaker wire pairs by color. The Accessory can be used in as T-harness or Loopback harness.
• The Fused Power Accessory: provides the 10 amp fused flow of constant 12 volts. and system ground.      

If its a speaker in your car, our harness will provide the high level signal on one end and let you build the rest from there. 

NOT ALL VEHICLES HAVE THE FACTORY WIRE SIZE TO HANDLE A LOOPBACK STYLE INSTALLATION! IF WE DONT OFFER A HARNESS IN THE LOOPBACK STYLE FOR A VEHICLE PLEASE USE THAT STYLE WITH CAUTION AND CHECK YOUR FACTORY WIRE SIZE! A simple solution is not always the safest!

• Measure Screen from BOTTOM LEFT to TOP RIGHT corners. This harness is NOT compatible with the 7" screen.
• THIS HARNESS WILL NOT WORK WITH BOSE systems. ( look at our Bose harness if you have a Bose system)

Thank you 😁
