CPU-95 DIGITAL IGNITION SYSTEM
11.0 PRIMARY WIRING
11.1
The main wiring harness (293023-x, 293026-x, 793012-x, 793015-x or
793022-x) connects the Ignition Module to the engine junction box.

Refer to
the harness. Insert the connector into the Altronic CPU-95 Ignition
Module receptacle and tighten hand-tight; then carefully tighten an
additional one-sixth turn with a wrench.
Referring to applicable
ing order below:

11.2
Connect the harness leads in the junction box in accordance with the
engine's firing order. The leads from the junction box correspond-
ing to the above system outputs connect to the ignition coil positive
(+) terminals. The "J" lead and the common coil ground lead(s) con-
necting the negative (−) terminals of the ignition coils must be grounded
to the engine in the junction box. Make each ground connection in
the junction box to a separate bolt so that the ground connections
are not stacked on top of each other. On V-engines, run a separate
common ground lead for each bank.

11.3
Primary wire should be no. 16 AWG stranded, tinned copper wire.
The insulation should have a minimum thickness of .016" and be
rated 105°C or higher. Irradiated PVC or polyolefin insulations are
recommended. Altronic primary wire number 503188 meets these
specifications. All primary wiring should be protected from physi-
cal damage and vibration.
11.4
If two ignition coils per cylinder connected to a common output are
used, use PARALLEL WIRING as shown on
11.5
All unused primary wires should be individually taped so that they
are insulated from ground and each other. The unused primary
wires can then be tie-wrapped together for a clean installation.
