My Check Engine light came on
and gave a code indicating a problem with the coil. After testing
the coil and realizing that it was way out of spec, I decided to replace
it with a High Vibration Blaster coil from MSD. While I was at it,
I decided to pick up a MSD 6A Ignition System. The 6A system will
fire a spark plug multiple times rather than the factory single ignition.
This will help provide a more complete combustion of the fuel for
better fuel economy, better throttle response, more power over all
RPMs and smoother idle. The Blaster coil outputs more energy and more
voltage to the plugs so you get even better firing. Both components
can be used individually as well.

Any 6 Series will work, this is
the base model |
MSD High Vibration
Blaster Coil |
8222
|
Any Blaster Coil will work, the
Blaster 3 does not require use of adapter part 8805/84039 |
| MSD Coil Bracket |
8213
|
Any universal coil bracket will
work. |
| MSD High Vibration Mounts |
8823
|
Not required, but recommended unless
using MSD 6 Off-road. Helps with mounting on uneven surfaces.
Part # valid for 6 Series Controllers |
| MSD Power Tower Adapter |
8805 or 84039
|
If HEI style terminal required,
must for late model Rams with Blaster Coils, except Blaster
3. 8805 is pack of 9 adapters but only one needed. 84039 is
single adapter with MSD 8.5mm SuperConductor replacement coil
wire. |
For late model V8 Dodge Rams, you do not need
any additional parts. The instructions say that you may need a Tach
Adapter, Pickup and some other items, but they are not required.
Non-94+ Ram applications need to check with MSD for additional parts.
Installing 6A with factory
coil:

MSD 6A with wiring harness and template I had to make.
I decided to mount the 6A on the drivers side
fenderwell under the hood. Since I also needed to mount the new
coil somewhere because the location of the factory coil does not
facilitate the Blaster coil, I put it there also. First I had to
remove the fenderwell liner.
Then, using a cardboard template, determined
where the High Vibration Mounts needed to be located. The mounts
are nearly 3/4" tall so they also helped me avoid a small hump
right where the 6A was to be located. I drilled the first hole from
the top to set the position.
Then I matched
the template on the under side to the first hole I just made. Drilled
the remaining holes from the bottom because the power distribution
center would not let me keep the drill vertical so it kept slipping
on the sheetmetal.
Once the holes where drilled
and deburred, I attached the mounts using Loc-Tite.

Mounts installed awaiting 6A
Mount the 6A to the High Vibration Mounts
and spread out your wires. You do not need any of the loose wiring
provided with the 6A.
For late model V8 Dodge trucks, you simply need to splice the 6A
in series with the factory coil trigger wires (Green/Grey and Grey).
The Red/White 6A wires connect to the "computer" end of
the coil trigger wires, while the Orange/Black wires connect to
the coil itself. Then connect the 6A power and ground leads as required.
I decided to cut the coil trigger wires near the coil connector.
I then soldered extensions to the "computer" end and wrapped
it all in convolute and routed it back to the 6A along the cowl.
I then soldered the coil connector to some wire, wrapped those and
routed them with the "computer" end back to the 6A. The
end of both sets of wires had male spades crimped on. This allowed
the 6A to connect to the new extensions. Once connected, wrap everything
in electrical tape. Also, if the 6A were to ever go out, I made
a set of jumpers to connect the extensions to bypass the 6A.
Installing
Blaster coil:
If you are installing a new Blaster
Coil at the same time as the 6A, mount the coil bracket when you
are mounting the 6A. I decided to mount the Blaster Coil on the
same fenderwell near the 6A. The High Vibration Blaster Coil is
fully potted so it can be mounted in any position unlike standard
oil filled coils. Be sure the coil wire from the distributor can
reach the coil as well as the Orange/Black wires from the 6A.
If your application requires HEI style terminals, install the Power
Tower adapter if needed. If the 6A is connected to a factory coil,
unplug the Orange/Black wires and reroute them to the Blaster Coil.
You can leave the factory coil as a back up. Reroute the coil wire
to the coil and you are done.
If you are not using a 6A and just installing a new Blaster Coil,
you need to splice the coil trigger wires to route back to the new
coil. If you want to keep the factory coil as a backup, then solder
the "computer" end trigger wires, the factory coil connector
and the wires to the new coil together. Unplug the factory coil,
and connect the new coil to the new extensions and route the coil
wire to the new coil. If the new coil fails, unplug the coil wire
and trigger wires from the and coil, reroute the coil wire back
to the factory coil and connect the factory connector back to the
factory coil.

Installed MSD 6A and Blaster Coil. The white wires
are from another device.
