Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
To by pass the amp [ Joseph  Oct 27, 2018 ]
A
because after much research and buying the wrong harnesses, I came to your website and this is what it says I need. [ kenneth  Oct 18, 2018 ]

great service by Mac.....he knows his stuff......... [ Gregory  Aug 21, 2018 ]

May need [ Greg  May 04, 2018 ]

This appears to be the closest thing to plug and play for Lexus GS400/300 owners out there, there looks to be very little splicing done, perhaps 3 wires instead on virtually the entire loom of the other harnesses. Plus you won't have to relocate pin positions! Also the added length is there that is needed to get from the back of your new head unit to under the glove box at the location of the factory amplifier which must be bypassed in order to get your aftermarket receiver to work.

Power, ground, and memory. The other wires by- pass the amp for the speakers.
