Grave digging, but same question.

hi iv just brought a corsa montana to modify and iv noticed that it must be the most basic of all corsas ever built. It had no fag lighter, no boot light no rev counter no front tweeters no rear speakers and basically its kinda shite. But iv managed to get the rear speakers sorted cuz all the wiring was there to just put some in. But i have just bought a boot light switch and the wiring is there 4 the switch but i cant seem to find the wiring that goes to the light, was planning on wiring up a few neons for the boot but dont no where to wire them to? can someone email me a wiring diagram as i was planning on upgrading the dash for the gsi/sri one which has a rev counter.
