Ok get a standard Bosch 30 amp SPDT relay. There will be 5 numbered terminals on it:
Here is where you should hook each terminal to.
85-----Ignition wire (usually a thick black wire with a yellow stripe on most Honda/Acuras located at the steering column harness. It should test to only have power when the key is in the run position)
86-----Hook one side of your arming switch to this terminal (86)and the other side of your arming switch to a chassis ground.
87a---Red wire on the ZEX NMU
This way the NMU will get its power from the battery but will only get power when the key is in the run position.
