Alarm wiring help needed
No alarms when key is turned on. Voltage at alarm purple is 12.8, voltage at alarm tracer is 12.0. No voltage at either with key off. Now the details, 1997 454 Magnum EFI. No longer injected, removed injecter half of harness. Did not cut or splice anything to use for carb application. Alarms never worked before EFI was removed. Buzzers are new this morning. What am I missing? Really don't want to put aftermarket alarm on if avoidable. Missing ground at engine end?

When the tan with blue tracer gets grounded the alarm sounds. Check you oil press switch only one that should alarm key on engine off.

I got it. Thanks lil red. Needed a wire from a plug that used to go in EFI harness. Good thing I saved all that stuff.
