FYI MSD rev limiter
1. If yours (like my 90) has magnetic pickup use that diagram in the MSD manual, but don't pay attention to green vs white wire. Only pay attention to the + & - in the manual and the corresponding P & N on the ignition module.
2. If you locate the limiter far away enough to need extensions for the wires, don't run the extension for the violet wire (that goes to the magnetic pickup) in a long plastic conduit next to the other wires. This will cause irratic rpms, even if rev limiter itself is not connected to any of the wires. You can run it along side such a conduit, though.
