is the white plug for the under hood fuse box? it is a 2004 gto t56 in a datsun also are these the wires for making my new fuse block? i received a print with the engine that shows a orange/black wire going for BCM fuse. the white plug has two orange wires one bigger than the other and a orange/white but no orange/black. when i turn on the key or turn off to shut down engine which wire would that be. i have all gauges working by way of old sending units and can crank the engine with the key and installed a clutch safety switch and a impact shut off for fuel pump. all those are tested and work and i just need fuses and on off for engine i think. thanks
