Has the harness been converted at all yet?

Factory 240s don't have ignition coil relays, so you have to modify the harness for one. Most conversions simply tap the ignition circuit off of the main power circuit (black/red). However, adding in the relay is pretty easy IMO. Just need to run a dedicated power to the gated side and have the selenoid tapped off of an ignition switched circuit

Thank you, so I should just turn the key on and check for power from the blk/red wire coming from the ecu?
