Do you know if the engineer could test it at work easier than it would be for me to do it?

Probably, if the engineer has a +12 volt DC supply, and can connect it to the relay terminals, as follows:

• Terminal 15, gets the +12 volt input that is connected to all 3 of the 87 output terminals when relay is energized

• Terminal 86, is to be connected by a momentary switch to terminal 15, to simulate the shifter switch button

• Terminals 31 and 85, are both to be connected to -12 volt "ground"
(85 is normally grounded thru the 4th gear switch, to control when OD relay can operate)

• An indicator (+12 volt light, buzzer, etc.) can be connected from any of the 87 terminals to the -12 volt ground, to show when relay is On or Off. This is like the dash indicator, showing that +12 volts is going from relay to the OD solenoid.

• Whenever the Momentary switch between 15 and 86 is pressed, the relay should "toggle" or change state between On and Off

Hope this helps.
