AFTERBURNER SWITCHABLE COIL
#140025
INSTALLATION INSTRUCTIONS
FORM 1647 02/05
Reading these instructions before starting the installa-
tion process will ensure that you will be able to take
the maximum advantage of all the performance that
your ACCEL Afterburner switchable coil was designed
to deliver.
The ACCEL Afterburner switchable coil is designed to
work on most vehicles equipped with a distributor and
a single coil type ignition system. It will work with the
stock vehicles ignition controls as well as most after-
market inductive storage as well as CD type ignition
control boxes.
In the normal mode the ACCEL Afterburner switchable
coil is designed to boost the amperage available at
the spark plug for improved low RPM engine perfor-
mance, maximum load conditions such as when
towing as well as helping to maximizing your fuel
efficiency. In the switched mode the ACCEL
Afterburner coil is design to boost voltage at the
spark plug for improved high RPM performance under
higher cylinder pressure conditions typically found
when under boost or using nitrous oxide as well as
helping to eliminate high RPM misses.
NEVER switch the modes of the ACCEL After-
burner coil while the engine is running! During the
time it takes to switch the ACCEL Afterburner coil
from one mode to the other, several ignition events
could be missed if the engine was running, even at
idle speed. This could cause an engine miss-fire
and resulting in exhaust and/or intake system
damage. Any vehicle damage that could result
from switching the ACCEL Afterburner coil while
the engine is running will NOT be covered under
the product’s limited warranty nor is any coverage
of said possible damage is implied.
Due to the high-energy output, the ACCEL Afterburner
switchable coil is supplied with an ACCEL 300+
8.8mm universal coil lead. The extruded aluminum
housing/mounting bracket is designed with cooling
fins for efficient heat dissipation. A mounting/
installation hardware kit is included. A universal
wiring harness is also included. This OEM quality
harness is designed to work with most vehicles’
engine compartment layouts.
Step #1
Choose an area on the fire well or fender well where
the ACCEL Afterburner coil may be mounted with no
interference from throttle linkage, air conditioning lines,
heater hoses, etc. and is no further than 24" from the
distributor. Please note that the ACCEL Afterburner
coil may not fit into your original coil’s mounting
location.
Caution: Before drilling any holes, please check and be
aware of what you may be drilling into. Be sure not to
damage a component that may be under or in line with
a mounting hole.
Step #2
Use the supplied fasteners in the hardware kit to
mount the ACCEL Afterburner switchable coil.
Step #3
The ACCEL Afterburner switchable coil comes with a
universal wiring harness. This harness must be spliced
into the vehicles OE wiring harness at the OC coil
connection using the butt splices connectors
supplied in the hardware kit. The yellow wire lead in
the ACCEL harness must be connected to the OE coil
(+) positive lead, while the black wire lead of the
ACCEL harness must be connected to the OE coil (–)
negative harness wire lead. Please refer to your
specific vehicles’ shop manual for the exact color
coding of the coil positive and coil negative leads
before cutting the OEM harness and splicing in the
ACCEL harness.
The blue wire lead in the ACCEL harness must be
connected to a vehicle 12 V switched ignition source.
