Fuse box/ Relay box wire identification

[mobbin240]

hey guys
im doing a battery relocation on my 1989 Nissan 240sx with a 93' SR20DET swap. long story short, I picked her up in bad shape a little while back with the stock KA24E. i need help identifying the 3 wire leads coming from my fuse/relay box on my passenger side wheel well.
they come out on the firewall side, right next to the fuel lines and filter.
what charge are these leads? All 3 leads are solid WHITE.
they connect to the alternator relay, headlamp fuses, and ignition switch.

so it could be a switched ignition, constant , or ground?


HHHHHEEEEEEELLLLLLLPPPPPPP!!!!!!
