Replacement Touch Panel

[orthrwi]

I have a 2007 LS460 L with a partially cracked touch screen. Lexus wants $2300+ to exchange the unit, and a non-Lexus touch panel can be purchased for around $40. However, I need to know if the original touch panel has a 4 wire lead or a 5 wire lead.

I would appreciate a response if anyone knows which touch panel would be correct. Also, if anyone knows someone in Wisconsin that could replace the overlay, I would like that information too.

This is the link to the vendor that I plan to get the touch panel from. (CAUTION- I don't know yet whether or not it will work.)

Thanks for any help.
