LIMITED ONE YEAR WARRANTY AND SERVICE PROCEDURES
GAUGE CONNECTION

A. SPEEDOMETER (Figure 4)
Connection of the speedometer requires using the vehicle's existing
speedometer cable. Route existing speedometer cable to rear of speedo-
meter and connect cable to 5/8"–18 male connector on rear of speedome-
ter. If the cable drive and/or the female threaded connector from the vehicle's
speedometer cable does not fit, you must buy an adapter and/or replace the
speedo-meter cable. See IMPORTANT note below. Connection adapters
and cables are available from most speedometer shops.
IMPORTANT: The speedometer is de-
signed for a 1:1 drive ratio (60 mph or
96,5 km/h at 1000 RPM) using a 5/8"-18
cable thread shaft. This shaft requires a
0.104” (2,64 mm) square female cable
drive. If the vehicle’s tire size or differen-
tial ARE NOT stock (original), speedome-
ter accuracy will be affected. It may be
necessary to change to a different pinion
gear to achieve the required 60 MPH at
1,000 RPM.
TRIPMETER OPERATION
The speedometer is equipped with a four-
segment resetable Tripmeter. To reset the
Tripmeter, rotate the Tripmeter reset knob
counterclockwise until the Tripmeter shows "0000".
B. HOURMETER / CLOCK (Figure 5)
NOTE: Hourmeter / clock operating voltage is 10 VDC minimum to 80 VDC
maximum (polarity-sensitive).
NOTE: Lead wires must be purchased separately. Use 16 - 18 AWG wire
minimum.
1. Determine routing for gauge lead wires. Use an existing firewall grom-
met, or drill a 3/8" (9.5 mm) hole through firewall to accommodate lead
wires. Install a rubber grommet (purchased separately) in hole, and
use shrink tubing to protect lead wires from chaffing or other damage.
2. Install and crimp or solder 1/4" female spade connectors (purchased
separately) on gauge positive (+) and negative (-) lead wires.
3. Connect lead wires to hourmeter or clock positive (+) and negative (-)
spade posts. Route lead wires through grommet in firewall.
4. Connect free ends of hourmeter or clock lead wires to vehicle electri-
cal system:
HOURMETER
For Negative Ground Systems
■ Connect hourmeter positive lead wire to a switched voltage source
in the vehicle electrical system.
■ Connect hourmeter negative lead wire to a good bare metal chas-
sis ground.
For Positive Ground Systems
■ Connect hourmeter negative lead wire to a switched voltage
source in the vehicle electrical system.
■ Connect hourmeter positive lead wire to a good bare metal chas-
sis ground.
CLOCK
For Negative Ground Systems
■ Connect clock positive lead wire to an unswitched (constant) volt-
age source in the vehicle electrical system.
■ Connect clock negative lead wire to a good bare metal chassis
ground.
For Positive Ground Systems
■ Connect clock negative lead wire to an unswitched (constant) volt-
age source in the vehicle electrical system.
■ Connect clock positive lead wire to a good bare metal chassis
ground.
5. Secure lead wires along their route to prevent damage from sharp
edges, moving parts or hot engine components.
6. Reconnect negative (-) battery cable.
■ For Hourmeter: Start and run engine for several minutes and ver-
ify hourmeter accumulates operating time.
■ For Clock: Observe clock for several minutes and verify time
advances.
