-18 gauge signal wire (Harness system 2 connects to factory amplifier & new amplifier(s) ) 

-Input / output Molex connectors (for plug and play system)

NOTE: This harness system was manufactured to work with tacotunes.com plug and play amplifiers. You can cut off the blue/black Molex plugs and connect them to several brand amplifiers. However, due to the large number of amp brands / models we cannot help with the installation process. 

To make the installation easier, we have listed the color/purpose of each wire in the harness system below. 

IMPORTANT: The factory wiring was not designed to handle a lot of power. We do not recommend more than 100 watts (RMS) on your stock wiring. Most amps are rated at 14.4 volts for their ratings. Toyota charging system is only 13.6. So you can easily use an amp rated at 100 watts RMS. 

The RCA Cables on this system connect to the input signal location on your new amplifier(s).

Each cable labeled for its designated use:

F – Front Speaker Signal

R – Rear Speaker Signal

S – Subwoofer Signal

This harness connects taco tunes TT65cs crossovers directly to our TXD line of amplifiers OR you can remove the black Molex plugs on the input jumpers and integrate just about any aftermarket amplifier and passive crossover set up.
