so let me get this straight demo,
you managed to cobble together a car but are stumped when it comes to a bit of wiring???
ive worked with 12volt auto my whole life and could tell you that all your problems are probably caused by corrosion from sitting so long or you having no idea what your doing!!
90% of people on this site are decent people willing to help out others, while the other 10% is little pricks like yourself who have nothing better to do than raise their post counts in between recess and second period at school.
your not the only one to have built a car here, you need to pull your fat neck in and just accept that its a little hard for someone sitting 1000kms away from you to figure out your wiring issues and give you the precise answer you want. if you did all the wiring as previously stated, you may need to have a good look at what youve fcuked up or maybe never attempt wiring again because to me it seems like you have N.F.I.
get a grip.
