## Description

Review: This harness works great for Honda Premium Audio systems. MUST HAVE PRE-AMP OUTS on your headunit! - Used this for connecting a JVC KW-NT500HDT to my 2008 Honda Accord EX-L 4dr V6 with 6-CD changer (now removed) and Premium Audio (did not remove). The JVC headunit has Pre-Amp outputs (Front L/R, Rear L/R, Sub L/R), and the ability to turn off the internal amplifier, cutting down on heat inside the unit. If your headunit only uses a built-in amplifier, and does not have pre-amp outputs, this is not the correct wiring harness. INSTALLATION NOTES: BE SURE TO CONSIDER THIS: If you want to use Steering Wheel Controls (and you are buying the Metra ASWC box or equiv), You should also buy the non-amplified wiring harness, and steal two pins out of it to add to this harness (use it as a suicide cable). This harness does not have these pins present, although the factory connector has them (i believe they are on Pins 5 and 16). I had to use wirecutters to destroy the plastic connector on the suicide harness, in order to steal the two wire leads and put them on this one. (BTW, DriveAccord.net was a great resource for my install) BTW: After much searching, the Reverse Signal wire is NOT present on the Honda Factory harness (for those wanting to install a backup camera). Apparently, there is one under the driver's kickpanel, but i just ran a wire along with my video cable back to the trunk and spliced into the reverse light wire itself. I ran these two cables underneath the center console, underneath the carpet, then underneath the back seat, then up underneath the padded vertical cornerpiece to the right of the seatback, then along the left side of the trunk. (I wish someone would have told me all this from the beginning, i could have saved a few hours) HOPE THIS HELPS!

### ⭐⭐⭐⭐⭐ Good product.
*by A***E on March 8, 2025*

Worked great.

### ⭐⭐⭐⭐⭐ IT WORKS for 2013 HONDA CR-V EX-L with premium sound and subwooker
*by K***R on February 26, 2023*

I don't know why amazon says this won't work, it's exactly what you need to change out the Honda CRV EX-L radio with premium sound amp and subwoofer. This doesn't do steering wheel controls or factory microphone and you need the antenna adapter as well, but it does the rest and was super simple to install.
