Honestly, I figured if someone had experienced the same issue, it would have been discussed in the SDS forum. Further, I know there are specific anomalies between the 240z, 260z, and 280z. However, If anybody can elaborate on why the crane ignition system doesn't require the trigger from the OEM electronic ignition module, then I would appreciate your insight.
Nigel, the reason I connected both wires is because the crane installation manual states to cut and connect any wire that was originally connected to the coil. Although I did not share this information previously, I referenced another datsun diagram to determine which wires to attach.
