Question Help Please
 

I got a 84 with a 12a and when I got the car it had an extra gauge cluster in it. . . I've looked all over the Internet and still can't find out what it is! Photo is attached. . From left to right in first ring = temp, fuel, and jeco clock. Second ring = volts and rpm. Third ring = mph (kmh), mileage, and trip. On rear on the board it reads : made in japan

Please can anyone tell me what I have ? ? Thank you

It's series 1 79 or 80. My guess would be a 79.
