Service Switch from CDI , works awesome , helps with diagnostics also.

Thanks so the big/fat red wire and the black wire are the power to the ecu .and the thin red wire is the key/ switch

you need to hook the battery - to the block and the battery + to the starter, which will provide +12vdc on the pin where the large red wire is, this will connect to the center post of the switch, then the switched +12 will return on the smaller red wire thats connected through the plug to the starter relay, your ecm, alternator, ect should be powered off the other wires connected to the + starter terminal where the battery connects.
