well, solved the fuse-blowing issue in the dash - appears the ground wire which connects to the cluster ground terminal located on the warning light circuit board, wasn't grounding the cluster... I ran a ground from the board to a metal portion of the dash and she lit right up. I did notice however from piecing 1 dash together from 3, that not every board was the same from gauge to gauge - on the warning light board at least, 1 didn't have the grounding terminal (a bolt-on piece) and on another, the light socket arrangement was different from the others (had 2 bottom sockets which were plugged from the factory, 1 on either side of the seat belt warning lens). Should be able to give the new gauges a shakedown run tomorrow :3gears: -
