Did a bit more on the headliner install tonight. I went the in-laws to borrow his carport and lights. I got maybe another hour done but I realised I left the crimp lugs behind so couldn't actually finish. See I am wiring up my Stato door trim lights and have to chop into the cables on the interior light. I have pretty much run the cables. I now need to tap in to the cables that run to the interior light and then I need to get some solder joiners from Jaycar as the cable that works the drivers side needs to have a join in it as I didn't buy enough cable, six or so months ago when I fed it through the door hinge boot, I was about 1 - 1.5 metres short.
However, on a positive note I did do a quick test and found that if I plumb in to both sides of the interior light, the courtesy light comes on. on the drivers side. I still have to run cable through the passenger side door hinge boot and up to the courtesy light on that side. However I will probably wait a week or two until I get my new mirror painted and fitted on the passenger side before I go to the bother of removing trims and running cables.
I found I had a bit of surface rust on the inside of the roof. So I buffed that off and hit it tonight with some primer. Tomorrow I will spray a bit of rattle can paint to seal it off before I finish getting the headliner back in.
