Mounting
(Shift-Lite model shown)
1) Loosen both bolts holding the shock strap to the mounting foot. Back both
bolts out until each is only one or two turns into the spacer.
2) Pass tach wires through shock strap assembly and slide tach casing into
shock strap assembly.
3) For external Shift-Lite models, position Shift-Lite mounting bracket under
shock strap as shown in image. Adjust Shift-Lite
(if applicable), tach, and mounting base to desired positions (see figure 4
for recommended shock strap position), and tighten bolts holding mounting
foot to shock strap to secure the assembly.
4) Make sure rubber section of shock strap seats properly to ensure proper
fitment. Check to make sure shock strap is approximately 1

between center line of strap and step of tachometer casing for best
mounting. For external Shift-Lite models, plug shift light into tachometer
connector. Plug is directional, do not force fit!
5) Recommended placement of external Shift-Lite (if applicable) is at 10
o’clock position. It is possible to place Shift-Lite in other positions in
accordance with driver preference and vehicle mounting requirements.
6) The special design of the tachometer base allows for a variety of mounting
possibilities. Attach the base using screws provided or use a pop rivet tool.

The tachometer is configured at the factory for 4 PPR. To change the PPR on tachs with three buttons, follow the steps below:
1. With no power applied to the tach, press and hold the SET button.
2. Apply power to the tach by turning the ignition key to the “Accessory” or “On” position. Do not start the engine! The pointer will move to a
position on the dial which indicates the default configuration of 4 PPR. Release the SET button.
3. Press and release the (erase) button to increase the PPR setting. Press and release the (recall) button to decrease the PPR setting.
See the tables below to find the pointer reading that corresponds to the desired PPR for your tachometer type.
4. When the pointer indicates the desired PPR, press and release the SET button to permanently store the settings and exit Configuration mode.
To change the PPR on tachs with two buttons, follow the steps below:
1. With no power applied to the tach, press and hold the yellow RECALL button.
2. Apply power to the tach by turning the ignition key to the “Accessory” or “On” position. Do not start the engine! Release the RECALL button.
The pointer will move to a position on the dial which indicates the default configuration of 4 PPR.
3. Press and release the red ERASE button to change the PPR setting. This will cause the pointer to indicate 5 PPR, then 6 PPR, then down to 0.5 PPR,
then 1, 1.5, 2, 2.5, 3, and back to 4 PPR. See the table below to find the pointer reading that corresponds to the desired PPR.
4. When the pointer indicates the desired PPR, press and release the yellow RECALL button to permanently
store the settings and exit Configuration mode.
