1. Disconnect the negative battery cable. 
2. Using automotive grade wiring (18 gauge), connect the red 
wire and the  POST to a positive 12 volt ignition 
(switched) source. It may be connected to the fuse panel, an 
accessory wire, or any positive 12 volt source that turns on 
and off with the ignition switch of the vehicle. 
  If wiring to an un-fused source, install a 3 amp fuse 
inline within 20 inches of the sources connection. You 
may obtain an optional “add a circuit” accessory. 
This component easily fits into your fuse panel and 
provides an additional fused power wire for 
accessories such as gauges. This is available at 
www.GlowShift.com or a local auto parts store.  
3. (Optional) The dimming feature of the Tinted Series 
decreases the brightness of the lighted gauge face 30%. Connect 
the orange wire to a positive 12 volt switched source. The most 
common installation is to splice and connect to the 12 volt 
positive headlight source. This step is completely optional. 
  This gauge should never be connected to a dimmer. 
Connecting the gauge to any type of dimmer switch 
unit will cause the gauge to improperly function. 
4. Connect the black wire and the POST and to any good 
(unpainted) ground connection. You may also route a wire 
directly to the negative side of the vehicle’s battery.  
5. Reconnect the negative battery cable. 
  If your gauge(s) do not illuminate or work properly , 
first check your power and ground sources.
