1989 parcar light kit problems HELP!! Please!

[parcarnick]

I am trying to install headlights and taillights on my 89 parcar. The kit i bought came with the harness. I attempted to hook it all up but the lights wont go on. I haven't connected the taillights could that be the problem? Also where the switch is for the lights there are 4 wire groups. two for the switch, and i'm not sure where the others go. one of them is a red wire and the other is white. The diagram says red goes to accesory power and white is ground. Where do i hook these too?? Also i don't have a converter i was attempting to hook it straight to the batteries but can figure out successfully use only two batteries as they are 6v each and i need 12v. Any help is appreciated. Thank you!!
