Ng 2.6 petrol wiring

[gberry56]

Hi everyone, I've got a 1989 2.6 petrol manual pajero and the wiring in the engine bay is a huge mess, just after a engine bay wiring diagram or something to help me sort it out, cheers, I seem to have no headlights, no power at all going to relay and no dash or interior lights either, any help would be great
