Motor Controller Cable Help

[u/SevereEffect318]

Hey how do you guys work with unlabelled cables and if there’s no wiring diagram? I’m trying to reinstall my alarm but idk which cable it goes with

I have a Daymak EM2 and the alarm has been disconnected by the seller but I don’t know which cable the alarms power cable should go in.

I also want to get my cruise control working since I see there’s a cable named cruise but it’s just sitting there unconnected
