ULTRA PERFORMANCE HEI MODULE

WITH REV CONTROL

PART NO. 35373

INSTALLATION INSTRUCTIONS

FORM 1561A 12/04

The ACCEL #35373 HEI Module is designed to
replace the entire 4 pin GM module and
connector/harness assembly in GM 4, 6 (even-fire),
and 8 cylinder HEI distributors. Only the GM
pickup/stator assembly will remain of the original
triggering system.

For optimum performance, use either ACCEL
#140013 or #140015 Brute Thunder SuperCoil in
street and racing applications.

INSTALLING THE MODULE-

1. After removing the cap and rotor assembly,
disconnect the 2 wires from the pickup/stator
assembly, remove the mounting screws, and
remove the GM 4 Pin module, connector/harness
assembly that it plugged into as an assembly.

2. Clean off the pad area of the distributor housing.
Use a surface or contact cleaner that leaves no
residue.

3. Put an even coat of the supplied heat sink
grease across the entire aluminum heat sink of
the module.

4. Place the module into position into place,
inserting the wiring harness into the notch in the
housing and snug the mounting screws down.
This will even out the grease film. Do not tighten
completely yet.

5. Use the supplied 8-32 screw to hold down the
back end of the circuit board. Once this screw
has been started into the threads, tighten the two
module screws down snugly. DO NOT overtighten!
Once these two screws have been tightened, then
tighten the remaining screw at the end of the PC
board.

6. Connect the two wires from the pickup/stator
assembly to the 2 spade terminals on the circuit
board. Note that there are two different terminal
sizes!

7. Select the number of cylinders using the 2 bottom
switches as shown in the diagrams below.

8. Select the rev limit using the 6 top switches.
The minimum rpm (with all switches in the "off"
position) is 5,000 rpm. For higher rpm limits, add
the value of the switches in the "on" position to
the base setting of 5,000. See the examples
below.

Note: If your distributor is showing signs of
bushing wear or if there is backlash in the
distributor/cam gear combination, the rev limit
my start 100 to 300 rpm below the rpm that you
have selected.

9. Reinstall the cap and rotor and set the ignition
timing. You may notice a slight timing change
now that you have installed your ACCEL #35373
HEI Module. This is normal. If your change is
substantial, you may have reversed the pick up wires.
