What wiring harness did you use?
Was it a specific V8 & automatic application?

The purple wire should run from the starter solenoid directly to the bulkhead connector.
The bulkhead connector inside half should have a purple wire running (from the same pin location) to the ignition switch in a manual trans application harness. An automatic simply breaks that purple power feed with an in and out connector for the NSS.
This is where and how you would extend the purple wire through the NSS in your shifter.
Any automatic conversion should include a NSS to prevent unintended movement of the vehicle.
Have you tried verifying power at the igniton switch connector for the purple wire?
At the bulkhead connector?
Are you using a schematic or did you do a wire for wire replacement?
