Focal Inside Toyota Y-ISO Harness

This harness is one out of the two must have in order too assemble the plug and play. I purchased to set up a focal 4.320 impulse amp in line with factory entune premium (non-jbl) head unit in a 2016 Toyota Tacoma.

Pros: Makes install very easy.

Cons: Very pricey must have.

Excellent quality plug and play cable. Can save a massive amount of wiring time. Very much worth the cost IMHO. Typical Focal quality product.

Pros: Though you have to connect two wires (ground and power) it's otherwise a plug and play amplifier!

Cons: For plug and play you may need a second harness (extension) cable if you are placing the amp anywhere other than under/within the dash. Which in the US can get kind of ridiculous in cost.
