Its funny how you go through stuff and you realize you have forgotten something important......like a horn....I 'm following this wire and I think what the hell was this wire for.....yep leads eventually back to the horn button, now I spend the next two and a half hours trying to find the part, getting really stressed out and it was in the very last place I could look.....car seat of my donor....could have sworn I had brought it into the house any way fitted now .....so I'm off to hunt down some relays cos I'll need one for the rad fan, wish I had kept everything in one place now
