Yellow wire on the MSD should go to the Blue wire on the Interface. The Brown wire on the Interface will be hooked up to pin # 85 on the N2O relay (there is a diagram at the end of the Interface Install manual). On the Interface Trigger +/- will be set to "-" and Trigger Power will need to be set to "on". If your MSD window switch is not activating the Interface won't be triggered.

The WOT switch can go inline on the wire from the arming switch to pin # 86 on the nitrous relay.
