FOUND ISSUE WITH E SERIES AMBULANCES WITH A KOER DROPOUT AND P1502-PTO ENABLED DTC ACTIVE. AMBULANCE MANUFACTURERS HAVE BEEN ACTIVATING THE PTO CONTROL BY CONNECTING THE SYSTEM DIRECTLY TO IGNITION SOURCE AT CUSTOMER ACCESS WIRING JUST LEFT OF DEGAS BOTTLE.WHAT I HAVE INSTALLED IS A SWITCHING RELAY THAT SWITCHES CLOSED(PTO ENABLED) WHEN IN PARK ONLY. I FOUND THIS RELAY TO IMPROVE SHIFT FEEL ALSO. A QUICK DISCONNECT WAS ALSO INSTALLED JUST FOR KOER CANCELING OF PTO FUNCTION. I CAN EMAIL DIAGRAM AND PICTURES OF CONNECTIONS IF ANYBODY NEEDS THEM.
