Awesome information, subscribing for later reference. Does anyone know the appropriate LED globe to replace the incandescents behind the dash and the interior? I would imagine they're different because they'd require different lumen outputs.

I have used a lot of google-fu including your search terms and can't seem to find anything on the JDM instrument gauges. They appear to have completely different wiring. If you could point out a link I would be grateful.

Lots of online references if you google... Lost of different configurations of the mr2... An enthusiasts best links / downloaded PDFs are; mr2 wiring diagram pdf and mr2 bgb

Google and the above manuals have all the info / references / pictures / diagrams / how to guides for getting most basic stuff sorted... Hope that adds to helping the knowledge base / reference

SW20 JDM Instrument Cluster wiring (mr2y)

Putting this here for reference. I'm not sure what cluster I have, it's a 'bitsa' with a 260km/h cable speedo (would have been 180k originally), and [used to have] a voltmeter, but I have tried to figure out the pin outs as best I could. Anyone with a similar cluster is welcome to add information. The part number on the white casing says 83010-17350 / 157310-0053. Colours of wires are to be used at your own risk, they just happen to be what's in my 1990 Japanese GT import.

Edit: A5 has a wire on my Japanese turbo, so I'm guessing it goes to the boost sensor?
Edit2: added pinouts for 1993+ JDM cluster
