That blue connector is "C28" or D on the Combination Meter pages.

Pin Color Function
1 Gr-L Raw speed signal from ABS ECU
2 B Tachometer signal from igniter
3 G-O Conditioned speed signal out to ECU, etc
4 Y-R Fuel Level Sender
5 O Fuel Level Sender
6 Br-B Ground for Fuel Level Sender
7 B-W Neutral signal
8 Couldn't find this on the diagrams, probably unused?
9 Should be unused
10 G Illumination power (10A Tail fuse) and other unknown functions
11 W-G Illumination variable negative voltaget (to rheostat)
12 L-Y To 15A Dome fuse (door ajar light and other unknown functions)

So, next try pulling these fuses individually:
- 10A Tail
- 15A Dome

And see if either/both reset it.
