For example, if the engine ignition puts out 4 pulses per revolution (8 cyl.), don't let go of the button until the pointer indicates See chart at right for details. Every two seconds, the pointer will step to the next major number (2 through 4). After “4”, it will start over again at “2” and keep cycling around until the button is released.

Mounting

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

⁄8 " (1.875") between center line of strap and step of tachometer

1 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.
