ToolRod, thank you ever so much for your reply. I do appreciate it.
Being sort of a visual person I would like to see pictures of the ashtray.
I am wondering if you just picked up a ashtray from the Lexus dealer, or found some aftermarket one. I bought a Prodigy P2 controller. It is a tight fit in the ashtray slot with the ashtray removed. Doesn't seem possible to put it in the actual ashtray. Maybe my Prodigy P2 is a little fatter they the unit you used.
I did manage to find the plug under the dash-that only took me a couple of hours.
Again, thank you.
I have not put pictures up either. Other members, how do we attached pictures to our posts? Thank you.
