Either rip all the tape off and follow each wire 1 by 1, or use a multimeter on a bleep test to see where they go. Some of those wires are spliced between there and the other parts of the loom, a red and black with 1 silver bar, a brown earth with 2 silver bars and a red and black with 2 silver bars. Could be a spliced wite and black earth in there as well, its been a few years since I ripped on apart lol.
