American IronHorse® 2005–2007 Model Installation
1. Be sure that ignition switch is off and disconnect battery.
2. Remove stock ignition module
3. Remove the stock ignition module connector by cutting the wires as close as possible to the connector.
Note: In the stock wiring harness, the crank position sensor, manifold absolute pressure sensor, and engine temperature sensor share a common ground
wire. This will not work with the Super Stock C ignition module and will require rewiring as described in the next steps.
4. Follow the black/green ground wires from terminal “B” of the engine temperature sensor and terminal “A” of the manifold absolute
pressure sensor to the junction with the black/grey return wire of the crank position sensor. Cut the engine temperature and manifold
pressure sensor ground wires at this point. The engine temperature sensor portion of the wiring harness may be removed or taped up.
It will not be used with the Super Stock C ignition.
5. Extend the ground wire from terminal “A” of the manifold pressure sensor to the location of the ignition module, strip the end, crimp on
a Deutsch® terminal, and install in position 4 of the Deutsch connector.
6. Be sure that any exposed wires are protected from the elements using electrical tape or equivalent.
7. Strip remaining wires that go to the ignition module and crimp on Deutsch terminals.
8. Install the socket terminals into the Deutsch connector according to the wiring diagram shown in Figure 2, next page.
9. Install seal pins into unused positions and locking wedge on Deutsch connector.
10. Verify using a multimeter that there is no continuity between terminals 4 and 9 on the Deutsch connector.
11. Verify that there is continuity between terminal “A” at the manifold pressure sensor and terminal 4 of the Deutsch connector.
12. Verify that there is continuity between terminal 2 at the crank position sensor connector and terminal 9 on the Deutsch connector.
13. Install Super Stock C and reconnect battery.
Installation is now complete.
