I purchased the conversion kit for my daughters 2004 Lexus RX 330 to get rid of the air ride because of a bad sensor and the sensor was a whole Lotta money and just wondering when I do the install what do I have to do with the sensors and the pump?

 

You either remove them or leave them. I'd remove them w/o cutting the wiring & possibly sell or swap them.......

 

If I unplug them will It throw codes or is there something else I need to do?

 

A good possibility, if it does I'd think the mil wouldn't come on thou. Possible suspension light, for that, I'd remove the cluster lense & cover the light w/ a very small piece of electrrical tape, you can't remove the light.
