If you are upgrading to an aftermarket radio in your 2007 or 2008 Acura TL this combination of harnesses simplifies the installation. There is no need to cut or splice any of the factory wiring. Instead to install your aftermarket radio simply color match the colors on this harness to the wires on your aftermarket radio harness. This harness combo allows you to retain your factory amplifier, subwoofer, backup camera and navigation. The radio you choose must have 5/6 RCA ports on the back labeled FL, FR, RR, RL,SUB if your radio does not have these outputs you will need a line out converter. You can find printable instructions here.
Our harness combo utilizes RCA connections to send a low level (0v-4v) audio signal from the back of your new aftermarket radio to the factory amplifier in your Acura TL. Our harness combo integrates with the factory amplifier to keep all of your speakers working except the center channel. If you wish to keep the factory steering wheel controls with your new aftermarket radio you may also need the AXSWC steering wheel control interface. If you do plan to retain your steering wheel controls, you will only be able to keep volume up, volume down, next, previous and mode. You will not be able to keep the call control buttons or navigation control buttons When you replace the radio you will lose the factory hands free functionality, the factory aux input and the factory XM radio along with your factory navigation’s audio prompts.
Please verify your factory amplifier is working and you aren’t having any volume issues before replacing the factory radio. If you are having volume issues please check out our plug and play amplifier. If you wish to bypass the factory amplifier in your Acura and power your speakers directly from your aftermarket radio check out the amplifier bypass.

FAQ.
- Will this allow me to keep my factory navigation working with a new aftermarket radio?
– Yes your factory navigation will continue to work but there will be no audio prompts. - Can I add an amplifier and subwoofers with your harness?

– Yes just follow the instructions provided in the radios owners manual or the cameras manual to complete the installation. - Can I use a random radio I found on Amazon or eBay that has an unknown brand?
– Most likely not. If the radio you purchased on Amazon is less than $100 it most likely won’t have all the features and ports needed for you to complete the installation. - Do I get to keep all my speakers?
– Yes all speakers are retained, except for the center dash speaker. - Do I get to keep my steering wheel controls?
-Yes but an additional part is required. The AXSWC you can find it here. You will get to keep volume up, volume down, next, prev and mode. The call control buttons will not be retained. - Why can’t I keep my center speaker?
– Most aftermarket radios don’t have a center speaker output therefore there is no audio source for the center speaker. We recommend disconnecting the center speaker during installation.
