Your image will not display for me when I click on it. However, from the thumbnail photo, that does not appear to be the Honda accessory keyless unit made by Kenwood.

In the 1992 NSX Electrical Trouble Shooting manual the keyless system arm output is on pin 9 / red wire and the disarm output is on pin 8 / yel wire. On the security control unit the arm input is pin 6 and the disarm input is pin 15.

Hopefully this picture works, kind of new to uploading pics to forums haha. But I think 18000rpm might have it with the japanese manual. Just going to translate it soon.

I don't believe that's a factory keyless system. See link in my signature for my Plug and Play system with new remotes

Yeah mine isn't factory, aftermarket but will need the colours code to disconnect it wired up to the alarm/immobilizer as a new alarm will be getting installed

Looks like you have a RHD? If yes, you're better off just buying a keyless system from @drew

From the instructions posted above you can assume that
BLK = GRND
RED = 12V +
GRY = Light Flash
The rest is hard to tell as it says refer to door diagram

Building your own DIY Keyless Notes. It should work for any NSX from 1991-2001.

The terminal relative positions are viewed from the wire side on female terminal connectors with the barb retainer on top, the terminals are numbered right to left. The male terminal connector is viewed with the barb on top and the terminals toward you. The gender of the plastic connector shell is opposite of the terminals inside: important to note!

The connectors are

I don't recommend cutting any wires on the OEM harness, it's not necessary and introduces long term points of failure. So DO ask if your installer is going to cut ANY wires, if so you might look for alternatives.

WhrdNSX sells and installs a PnP system in AU. The installation time is 10 minutes to 1 hour depending if you also want a light flash and a remote trunk release.

(No need to spend money, but if you do: I use the support for R&D on other NSX projects that we are gonna need to keep these cars on the road. If anybody wants to support The Cause: I am looking to buy core electronics in the area and a MVAC harness.)
