Jeep Wrangler 2005 TJ

[Spastro]

Hello all.

I have a 2005 Jeep Wrangler renegade edition. I believe its a TJ ?

Was looking to put in a joying single din 8.8inch head unit.

My jeep came stock with 7 speakers, Sub in the centre dash between the 2 front seats and amplifier. I am led to believe the amp is also in the centre dash.

The front dash looks exactly like the Cherokee XJ2000 dash they have on the radio link above.

I contacted the joying manufacture email on their site and the person who emailed me back from joying manufactures said "Sorry, we do not have the workable harness you need. you need to buy the harness which supports the original steering wheel control and your amplifier from other harness sellers".

I'm a little confused as as the joying site mentions this harness for jeep.

Does anyone know what I need to buy to have this stereo work with my Jeep stock speakers and amp?

Thanks.
