Why? Can you explain more pleaseIt is 0% likely this would be a plug and play project. You can't even plug an EX head unit into an LX.
Probably, but there's a slight possibility EX and EX-L have the same wiring since they have the same head unit without navigation.All the different trim lines use different wiring harnesses
Well, you can start by buying short term access to techinfo.honda.com (and the Acura counterpart) and staring at the wiring diagram for the various cars. But I don't think it will help; an RX head unit is going to be expecting to talk to RX control modules, which won't exist.where else can I get answers to my question, any suggestions? its becoming a challenging project and would like to try it
