So, I tend to be a tad impulsive. I ordered the hk enabler harness for my car, then decided on a full blown sq setup. So I now have an unneeded harness for sale. This harness allows you to replace the head unit, and retain the hk amp. Easy install. Asking $150 usd shipped. This is brand new. So new, it's still in the mail, On its way to me! I also have a factory head unit, and 100% functional hk amp available. From an 06.
I just sent you a private message. If you still have it, i'll take it. I spent a LOT of time today cursing HK!
