internal programming jumper
NOTE: The control module door must be removed to access the jumper.
In most cases, this jumper can be left in the OFF position. Some new vehicles use less than 12 volts in their igni-
tion 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 it will work properly with these vehicles.
The vehicles affected include many newer Dodge/Chrysler/Plymouth vehicles, such as the Neon, Cirrus, Stratus,
Breeze and LH-based vehicles.
