im new to this fourm an just bought a 2011 lexus is250 awd and was wondering if this trim comes with the harness for the center dash speaker or will i have to wire it up myself. any info would be helpful thanks!

 

The center dash speaker is the center channel surround sound speaker (used for dialogue/voice when playing DVDs) for cars equipped with the Mark Levinson audio option. I don't think cars without Mark Levinson audio have the harness, but even if they did, I don't think you would want to add a speaker there. All it would do is reduce your stereo separation.

 

I have had my dash apart and did not see any wiring harness for the center front speaker. My is250 does not have the ML stereo

yes, there's a plug/connector for the center speaker in a non-ml equipped IS , but it only goes as far as passenger junction connector.
