Programming jumpers
➤Light flash (+) / (-) polarity
This jumper is used to determine the light flash output polarity. In the (+) position,
the on-board relay is enabled and the unit will output (+)12V on the WHITE
wire, H1/2. In the (-) position, the on-board relay is disabled. The WHITE wire,
H1/2, will supply a 200mA (-) output suitable for driving factory parking light
relays
NOTE:
For parking light circuits that draw 10 amps or more, the internal jumper
must be switched to a (-) light flash output.
P/N 8617
or a standard automotive
SPDT relay must be used on the H1/9 light flash output harness wire.
➤ Tach threshold On/Off
In most cases, this jumper can be left in the Off position. Some new vehicles use
less than 12 volts in their ignition systems. The unit may have trouble learning the
tach signal in these vehicles. Changing the jumper to the On setting changes
the trigger threshold of the digital tach circuit so that it will work with these type
vehicles.
