Hey everyone,
I have been getting many requests for my DD conversion DIY guide that I did back in Spring 2004. This guide was originally posted on
www.g-owners.com but now is unavailable since that website is now non-existent.
Couple notes about this guide since I first created it.
1. You do not necessarily have to disconnect the negative terminal of the battery. Most installation instructions for any modifications/replacements to a car will advise disconnecting the negative terminal of the battery. It becomes inconvinient to disconnect and reconnect the battery when having to move the shifter to neutal or drive to remove and lift the heavy HVAC unit from its mount. BUT WHEN WORKING WITH potential live wires, specifically connecting the remote terminal amp power wire, having the battery disconnected is a good idea!
Do what you want, just use common sense.
2. When ordering the DD trim finisher and the JDM AC controller from wherever (Japan, Grubbs, Riverside Infiniti, etc) you DO NOT need the aluminum bracket as you can use your stock one.
3. You DO NOT need to disconnect clock and remove it completely. Just unscrew mounting screws and move clock to the side so you can access the anchor screw of the HVAC unit located behind the clock.
4. In step 27, you DO NOT need to remove this little trim piece as this will come out connected to the complete HVAC unit when you remove it. But, if you do break some of the little brittle clips of this little trim piece, another one should come with your DD dash finisher.
5. At any given time, you can connect (via butt connectors, soldering, crimp connectors, etc) your NN01 Scosche wire harness to your aftermarket wire harness.
**Note: Again, if you complete your DD conversion and then your AC malfunctions and goes cukoo for cocopuffs (i.e. runs hot with no ability to control temperature), there are 3 possible reasons why this is happening.
#1: (most common) you didn't reconnect the AC harnesses on the HVAC unit and dash side perfectly and correctly. Remember, the AC harness has those little brittle clips on the top and bottom of the harness that you have to remove and then reconnect carefully.
#2: when you dropped the panel beneath the steering column, you accidently (or maybe intentionally) disconnected or jarred loose the "in-cabin temperature sensor". This sensor is located behind that little 2x1" grill located near your right knee when you sit in the driver seat. You need to make sure this sensor wire was not jarred loose and is connected properly.
#3: you completely screwed the pooch and fried the AC controller circuit board when you attempted the dual climate control button resolder.
I have never heard of this done but I guess it is possible.
Good luck. Don't scratch that dash and center armrest paint!
All I ask is please don't abuse/rip off/plagiarize/take credit for my hard work! Thanks!!!
(I actually had a stupid installer take credit for the guide after I saw him using an actual printout of my DIY Guide at his shop. He couldn't believe I created it, what a bozo!)
