I installed a 411 some time ago in a 1997 chevy k1500

Most everything works fine execpt the following.

No Knock Sensor. Going to run new wire and new plug. Replaced knock sensor.

PCM does not power off when key is off.

I have to disconnect the battery and let it sit for 30 seconds. Then flash my calibration over.

I know these issues are wiring because ive put the same PCM in a different truck and didnt have any issues with it.

Any help would be appreciated.
