Changing the gauge configuration
The AEM Serial gauge comes configured with the black bezel, black pin guide, and the
black faceplate. However, a silver bezel, a silver pin guide, and a white faceplate are
also included in the gauge kit. To change the faceplate, pin guide, or bezel, orient the
gauge so you are looking at the faceplate. Rotate the bezel counter-clockwise to
unscrew it from the gauge cup. The bezel, lens, pin guide, rubber spacer, faceplate,
diffuser, and anti-glare shield are all removable. Reassemble the gauge as shown in
Figure 6. Make sure the small light holes in the faceplate, diffuser, and anti-glare shield
line up with the light sensor on the circuit board. Do not over tighten the bezel when
reassembling the gauge.
