Step 12. Install the small optical sensor support bracket on the bottom screw hole and attach the ground wire you moved out of the way on step 8.
The first photo does not show the ground wire attached. Do so before you go on to the next step.
Step 13. Install the trigger wheel on the shaft paying close attention to the flat sides on the shaft and the matching flat sides inside the trigger wheel.
Step 14. Install the optical sensor to the support bracket from step 10 and check for proper spacing and no rubbing/interference.
Step 15, Route wires out of notch in distributor housing making sure there is no interference with the moving parts inside the distributor and seal the opening with silicone sealant. Be careful to not get any inside the distributor housing.
Step 16. Install new rotor in same position as the one removed. You will notice in the photo, mine is a little worn. I have a new one in there now. It wasn’t available for the photo. (See step 2. :stupid: )
Step 17. Install distributor cap.
NOTE: If you are replacing spark plug wires put on new set following the proper firing order. (1972 US model is 1-5-3-6-2-4)
Step 18. Find a suitable mounting location for the control box. As you can see in the photo I mounted mine down by the frame rail directly under the coil. You will have to drill into the car to mount it there. If you don’t like to make any more holes then find some that will work for your application.
Step 19. Follow the instructions that came with the product to make the electrical connections. THEY ARE EASY ENOUGH TO UNDERSTAND.
NOTE: To clean up the look of my installation I shortened the red, yellow, and black wires when I installed my new coil.
Step 20. I soldered all my connections and used heat shrink tubing to make sure that they were good. I recommend you do the same if possible. Is seems the crimp on connectors always fail at the worst possible moment (Murphy’s Law) and they are sometimes very difficult to diagnose when there is a problem.
Step 21. Verify that all connections made were in accordance with the instructions and that they are tight and secure.
Step 22. Reconnect the battery and start the car.
Step 23. Bring it up to normal operating temp.
Step 24. Attach a timing light and verify timing and adjust as necessary to get optimum performance.
Step 25. Remove timing light.
Step 26. Take car out for a test drive. If all checks out okay, then enjoy your self installed maintenance free ignition system.
To give a cleaner more professional appearance, wrap the wires in a wire loom after everything is checked out and works.
I hope that this helps those who are looking to install the Crane XR3000 ignition system on their 240 Z. I welcome all feedback since this is my first write-up so any constructive criticism is welcomed. Just PM me and let me know.
Thanks for reading,
David Honeycutt
