I installed the JDM S13 DCC in my daily this weekend and figured id do a write up on it. As a basis i used this post on NICO by Beatupsx http://forums.nicoclub.com/zerothread?id=160285
I will try do go more in depth to make this install more simple. Some words will be quoted from that post.
^^ This write up is way more printer friendly, i suggest if you have a good idea of what you need to do print that thread and refer to mine if you have any questions, there are slight differences.

Here is the list of parts you will need.

1. JDM S13 Digital climate control unit

2. JDM S13 Digital climate control sub-harness

3. JDM S13 Blend door actuator
^^JDM only parts^^

4. Blower motor speed controller, i used the JDM S13 one, you can also use one "from a 92 Q45 but most mid 90's maxima with automatic climate control should work to"

5. Optional** JDM Thermo control amp ( i used the stock one with no modifications, not sure if it would change anything)

6. JDM aspirator tube(connects air box to cabin temp sensor) also from "mid 90's maxima with automatic climate control"

SENSORS
1. JDM Ambient air temp sensor ("you can get it from a 91 pathfinder and most mid 90's maxima"

2. JDM Cabin air temp sensor ("most mid 90's maxima")

3. JDM Sunload sensor ("most mid 90's maxima")

INSTALLATION

1. Wiring
The wiring for the DCC is very simple and can be done without any trouble. The only JDM wiring you need is the harness that plugs into the DCC unit. The sensors will plug into that and if you have the sensors with connectors it will make the install easier. There are 3 power wires and one ground that have to be spliced into the harness.

1. Constant +12v power. This wire is the single red wire with a single plug on the JDM DCC harness. I spliced this into the memory wire for the radio, it is Red/black stripe on the USDM chassis side of the radio harness.

2. Ignition on +12v power. This wire is Blue/Red stripe and is on the small 6 wire connector on the JDM DCC harness( see below ). I spliced it into a blue wire on the USDM Radio connector on the dash harness that has power with the ignition on.( see above)

^^ 6 wire connector

3. Ignition on +12v power. This wire is the Green/white stripe on the small 6 wire connector( see above). This wire can be disconnected at the 6 wire connector and re pinned into the large 16 pin connector( see below) in an empty spot. This spot has ignition on +12v that is already run the the USDM dash side so all you have to do is plug it in and it will work, no soldering.

4. Ground wire. This is the last wire you have to run. On the USDM side of the 16pin climate control connector there is a Red/orange stripe wire that needs to be grounded.( see below) I cut the wire a few inches from the connector and attached a ground eyehook and bolted it to the dash frame.
