OK. I know this is an old thread but I'm in the process of installing a pair of JDM Integra fold-in mirrors on my DA9 so I thought I'd revive it rather than making a new thread or "How-To".
I was out at Pick n Payless a while ago, and an unusual Integra caught my eye. It had a Personal Import tag in the engine bay. It was a DA5.
I looked it over, it hadn't been there long and noticed the mirror switch had a little extra button, and immediately recognised it as the activation for JDM fold-in mirrors.
I grabbed the mirrors themselves and the switch, then came home to do some research. It was then that I found out you also need the relay box so it was back out to PnP the next day.
It was pouring rain, and I had to virtually remove the whole dash to find the small relay box tucked up high on the passenger side. Needless to say I got soaked but I was determined to get as much of the necessary wiring as I could. It's usually all the same price anyway.
Now I figured I'd do a good "OEM" style job so I took all the door wiring from both sides, right through to the door jamb. I grabbed all the wiring behind the switch (basically the complete dash wiring - I thought I might as well seeing as how I'd removed the dash anyway). It included some other "Extra" switches like foglights.
When I got home I noticed that the large "clear" plug that goes into the fuse box under the dash is way different than the Aus-spec one so this really negated using the JDM dash harness as I wasn't going to try and find where about 30 wires went under the dash. Anyway, the green Aus-spec mirror plug is exactly the same as the JDM one - it has all the same wires so if you go to do this don't be put off by the US installation how-to's. Their plug doesn't have the extra wire needed to fold the mirrors in (as seen in the photo below - it has 7 pins; JDM/Aus-spec is full 8 pins)
So this is what you'll need to do this job:
1. The mirrors - actually you don't - you only need the motors inside. If you want JDM glass you can keep those but I replaced them with the flat Aus-spec glass.
I wasn't going to repaint the JDM mirrors as they were pretty nasty (original Milano Red and someone had painted them gloss black) so I just transferred the motors to my mirrors.
As it turned out it wasn't that easy as someone had tried to cure a wobbly mirror by using Locktite Blue on the three small screws underneath. I ended up drilling them out and finding replacements. This wasted about two hours.
2. The relay box under the passenger side dash area. Make sure to get enough wiring with the blue plug to be able solder join.
3. The wiring from the doors, up to the door jamb - Aus-spec is 3 wires; JDM-spec is 5 wires.
4. The dash switch with extra button (seen below against standard switch). My switch isn't as fancy as this, and the button is on the other side (This photo is from a US install).
PS. These aren't my photos as I've already got the wiring in the doors and attached to my mirrors before I found this thread and writing this.
I'll take some photos of my install as soon as I can.
I did some continuity testing on the Aus-spec plug at the under-dash fuse box and I found out that all the wires have "active" functionality so it's really only the one wire - the one that makes the mirrors fold-in - that has to be activated. It's on the switch but I think it terminates at the fuse box.
This will mean leaving all the original wiring in place (up/down and left/right on the mirrors), and activating the fold-in by getting 12V power and an EARTH to the mirror relay, joining the wires and splicing into the dash switch.
