hey guys just recently bought a 2003 ls430. I acquired a celsior radio head unit from a friend didn't install it yet but when I was looking at the 2 ports where the radio harness goes in I found that the smaller connector on the left of the main harness is different from my radio. the main one plug looks like there the same size but the one off of the celsior for the 2nd connector looks wider unlike the pioneer which is skinny and narrow and has 2 wires going to it. l I have a non nav, non ml. anyways. what does the 2 wires control. its a red and green wire and will the head unit still work if not plugged in? I was looking all over the search forum and google and could not find a decent diagram to see what those 2 wires go to or come from? just trying to see is the radio will work. they look exactly the same just that small 2 wire connector is different size from the celsior.


thanks guys,


stephen

 

Anybody.

Thanks

 

Here's a sketch of the 2 connectors on a 2003 LS430 radio. Does it look like yours?

 

yes it does. Your a Life saver. Thank you so much. Seriously. I appreciate it big time!!

 

You're welcome. Attached is the electrical schematic for the 2003 LS430 radio and player. Good luck with your project.

 

You wouldn’t happen to have the head unit schematics for 2005 ls430?
