Ignition tray

The Ignition tray is made from 1/8” aluminum and has a 12” X 12” footprint. The tray has a 3” tall front lip
for product identification. This lip will be facing the rear of the vehicle and is acceptable to hang off the
edge of the dash. The bend for the lip has a .50” radius so the overall front to back length of the tray is

12.65”

The coil terminals hang off the right and left side edges of the plate by around 1”. Special attention should
be paid when positioning your plate so the coil output terminals are at least 1” away from chassis ground to
prevent possible arching to ground.

The tray has 4, 11/32” holes that are 1” in from the corners of the 12” x 12” footprint. This makes the hole
center spacing 10”. We recommend using 5/16’ or smaller studs and washers to allow for slight variations.
The components are bolted through the plate so there are bolt heads on the bottom of the tray. We
recommend using .25” thick spacers or washers under the plate so the bolt heads do not contact the dash.

The overall height from the bottom of the plate bolts to the top of the front ignition box is 3.75” tall.
Special attention should be paid so the corner of the front ignition box does not hit the window of
the car.

Wiring

Each ignition box has a 2-position male weather pack connector for the power and ground wires as well as
a 6-position female weather pack connector for the remainder of the wires. Each coil has a 2-position
female weather pack connector. All connectors exit the tray towards the center of the dash. The tray has a
.25” grounding stud on the left side when looking at the top of the tray. We recommend running a ground
strap from the roll bar to the .25” stud to eliminate the possibility of electrical interference.

The part numbers listed below are for the MATING harnesses (i.e. the vehicle harnesses) that the racecar
will need to mate up to the Mallory CT Pro ignition system.

Distributor Wiring

Mallory CT Pro Ignition Boxes were designed to accept one magnetic pickup per ignition box. We
recommend using a dual pickup distributor with each pickup going directly to one ignition box. Paralleling
one magnetic pickup per two CT Pro ignition boxes could result in extremely retarding ignition timing.

If you are using a dual pickup distributor and have a switch to select between each distributor pickup, make
sure it is not wired to parallel one pickup per two ignition boxes.
