HVAC controls

[RobS763]

Hey everyone Im sure this has been brought up before but i can not find the exact answer im looking for. I have a 99 ex with the regular push button HVAC controls, i would like to switch to the digital control unit. Direct swap or is there anything i need to know? I read on one post that the clock and hazard button were different, but i thought the digital set up was part of the EX package. I may be wrong...

I also know that the Manual controls dont have a sunlight sensor or a auto climate temp sensor.

i guess what i really would like to know is if the wiring is still the same...plug and play...or will modification be needed?

These are the diagrams for the Auto system versus the Manual system.

youll have to add all the sensors from the auto climat control

As well as adding in the passenger side Relay, It would be easier to source the whole harness if you aren't comfortable tapping and modifying factory plugs.
