I too have more faith in Haynes than the CD's I bought off e bay took 3 attempots( separate cds costing about £20 0 before I got a set that would load. Even now I can't find any actual wiring diagrams as there are cin the Haynes manuals. Perhaps Laguna II owner can point me in the right direction.
BTW I find thios forum a lot more helpful than P*****RS more polite as well if I post in wrong place. The knowledge section is a great help. My sincere thanks to all who subscribe.
