I have a 325 tree and im wanting to wire in a TRICO micro-drop into the machine so when the m8/m9 command is used the system will operate. I am trying to make sure where to look as I have no wiring diagram. Or if someone has done this swap before..
I did one around 1994
I used a 3 position toggle switch, mounted in the rear door. Pull the + line off the contactor coil for the coolant pump. Place wire on center tap of the switch. Use one of the other taps to power your solenoid, with the other tap back to the coolant pump contactor. Now take the other wire from the solenoid back to the common. Now you have coolant and mist, so you dont loose any capability. Double check the voltage, but im pretty sure it was 110V, so you need a matching solenoid.
