Welding
To avoid any damage to the HYFIRE
®
6EZ Ignition Control when
welding on the vehicle, disconnect the positive (red) and negative
(black) power cables of the HYFIRE
®
6EZ Ignition Control. It is also
a good idea to disconnect the tachometer ground wire
as well.
Distributor Cap and Rotor
We recommend installing a new distributor cap and rotor when
installing the HYFIRE
®
6EZ Ignition Control. Be sure the cap is
clean inside and out, especially the terminals and rotor tip. On
vehicles with smaller caps, it is possible for the air inside the cap
to become electrically charged causing crossfire which can result
in misfire. You can prevent this by drilling a couple of vent holes
in the cap. Drill the holes between terminals at rotor height, facing
away from the intake. If needed, place a small piece of screen
over the holes to act as a filter.
Hyfire
®
6EZ Diagnostic LED (Not available with rev limiting
ignition 6EZ RPML). On the end panel of your Hyfire 6EZ ignition
there is a small hole. Behind this hole is a red LED indicator.
The LED will flash when receiving a proper trigger signal from
the vehicle. If, after a normal power-up, the LED doesn’t flash
when cranking the engine, you should check your triggering
circuit for problems. If the LED flashes
when the engine is cranked, but there
is still no spark, the problem lies
somewhere else.

6EZ Cylinder Selection
Your HYFIRE
®
6EZ Ignition comes from
the factory set up for 8 cylinder
operation. If you want to use this
ignition with a 4 or 6 cylinder engine,
you must first remove the four screws
that hold the endplate with the LED hole. Once
the endplate is removed, you’ll see the end of the
circuit board. Look for the two-section switch. To select
4 cylinder mode, move the switch marked "1" to the "ON"
position. To select 6 cylinder mode, move the switch marked "2"
to the "ON" position. If both switches are "OFF", or both are
"ON", the ignition will run in the 8 cylinder mode. See Figure 1.

MOUNTING
The HYFIRE
®
6EZ Ignition Control can be mounted in any
position. If you mount it in the engine compartment, keep it
away from moving objects and heat sources. Do not mount
the unit in a closed area, such as the glovebox. When you find
a suitable location to mount the unit, make sure all wires of the
ignition reach their connections. Hold the ignition in place and
mark the location of the mounting holes. Use a 1/8" drill bit to drill
the holes. Use the supplied self-tapping screws to mount the box.
The ProMaster
®
e
Performance Coil can be mounted in any
position. We recommend placing it within 24" of the distributor
for ease of wiring.
