The cluster pinning changed for the build year 1995. In addition, Honda changed the way they count the pins somewhere along the way.
If I remember correctly, the physical ETMs from 1991, 1997 and 2002 all contain cluster information.
Capacitor failure is an interesting technical topic. While seal failure and leakage are well known cases, the PCBs in the NSX are affected very differently. The ones in the engine ECU seem to last forever while others fail very early, all of them rated for 105 °C and well known brands. I'm still...
You need to apply 12 V to either the left or the right hand pin of each connector at the hydraulic block. One activates the inlet, the other the outlet valve. Note that the outlet valve opens when supplied with 12 V but the inlet valve closes.
The stickers on the radio are different from the page in the manual. They show the right and left channels at the same pin for EUDM and JDM:
Note, the picture on the sticker is flipped 🙃
Lovely color - the red NSX is the only non-yellow car in my family :)
Standard reminder from the electronics guy - all capacitor leakage related CCUs checked/rebuilt?

The capacitors are mostly the same in all build years but differ between subwoofer and door speaker. Bose did change the layout slightly over the years. Proposed way is to take out your amplifier boards, check each one against the list in the write-up and order accordingly.
Hi R factor,
That's almost guaranteed to be CCU module damage caused by capacitor leakage:

I assume you are located in the USA. Best to get in contact with member @Briank...
The oil pressure gauge is identical in all versions of the cluster I worked on so far (USDM, EUDM, JDM). It simply displays a given voltage on the oil pressure pin.
