The late model Acuras will require you to go with a custom radio install kit, regardless of what you are installing.

The dash panel replacement is usually customized to fit your single DIN Acura TSX radio or aftermarket stereo.

Of course this will change slightly if your TSX is equipped with navigation already. When upgrading your Acura TSX navigation system, you can use a plug and play stereo wiring harness to get the job done. If you are reinstalling your factory Acura TSX stereo, you’ll need your radio code from Acura / Honda.

    • Hi Paul, setting the timing is easy to do in your Honda. Do you have a 3.0 liter J series V6? or a 2.4 liter K24 DOHC 4 cylinder? let me know and I can help you out! You won’t need to adjust much however, timing is fairly straightforward to do! Thanks for commenting Paul

  2. There was a guy lookin at a k20 I went got a battery hooked up a hot wire to the sol.on the starter and took a flat head screw driver and fired up the motor for him it started rite up but the headlites started flashing and horn was beepin engine sounded really good he got that engine for 150$ also..mine had 78,0000 miles I said no im rebuild ing I know its good its a 225 hp v6..

    • Hey Paul, again slightly confused… the K series engines are DOHC 4 cylinders that are transverse mounted. are you looking at the J series V6 that’s in the accord / odyssey and others?

  3. Where can I find a 2nd Gen TSX Wiring diagram? You mention some wire colors but I can’t find a diagram anywhere. I am looking to tap into the sub woofer signal wire going to the amp. I was hoping I could get a better sound by doing so rather than using the LOC feature of the new replacement amp I’m using. I have a 2009 TSX Premium sound w/ELS
