Hello all, I'm atempting to do the digital climate control swap myself and have found vertually no info on how to do it besides the 2 confusing posts in this forum.
I have it working completely except the blower motor. I'm having trouble with that part. So I'll just give what I can now to help everyone else out.
First off you need the subharness from the digital climate control. For the unit to turn on and cycle through the havac options you need to swap these wires:
Sub Harness: Red -> to 3 red wire harness on the radio, connect it to the -> Red/Black wire (BAT+) Green/White -> from 7wire plug and insert it to the large white harness next to the Green/Yellow wire, the corresponding 240sx wire is -> Blue/Orange (IGN+)
240SX Harness:
Red/Yellow -> from large white harness to -> Chassis Ground (GND-)
Unplug the factory fan realy.
This will allow the unit to function and cycle through the havac options.My problem lies within the pink wire, I think this is a ground. When the Analog unit is pluged in when in any operation position its grounded (no power). When you plug the Digital unit in it becomes positive and I think that this is the reason why the blower motor will not work. Anyone know how to fix or wire this properly????
This instructions are for 89-94 S13 240sx's using S13/180sx digital units.
I also attached a pic of the wiring for everyone. Thanks, Eric
