Does anyone sell the R Spec Data System harness by itself or do you have to buy them with the controller? i seen one for sell but the harness was for a different year Lexus.

 

ebay has just about evrything on there did you try there. Btw what year is your car

 

It's a 2001 LS 430 UL. I'm trying to figure out the best way to lower my car. I want to tuck 20 inch tires. Trying to get the car to ride smooth as possible and not have it clunk or make noises going over speed bumps or going up driveways.
