41 PC engine sync and alarm wiring


Hey gang - So my 41PC has been annoyingly false alarming the high temp/low oil pressure buzzer about every 2 minutes regardless of what the motors are doing and what the oil pressure and temps are (this had been happening to the previous owner as well). So, I opened up my dash to discover the problem and fix it. Well, when I did that my port ignition wiring snapped off the housing and now I found the engine sync wire dangling in place and I do not know where to attach it to. Is there a wiring diagram for this dash so I can figure out how to reconnect everything properly? Has anyone else had this faulty alarm issue? Any help is appreciated, thanks!

Our new to us 41PC also gets the false alarm buzzer intermittently. I push the reset and it goes away for a while but comes back again. I have not had a chance to even look at it last season, something for next year. If anyone has ideas, I would love to hear them.
 
I have no alarms at all and was told by Mechanic that with 2000 Volvo Power and drive by and shift by wire which is not Volvo - there are no Alarms. Anyone with same year and power have alarms?
