1990 240sx re-wire questions

[maniac240sx_7]

I am attempting to do a re-wire to my hatch 240sx.
I will only be using turn signals, brakes,headlights.. everything is going to be turned on manually by a switch. (Fuel pump, battery, push start, lights,fans,etc. ) I am lost on what needs a relay and what can just be hooked to a fuse. I am trying to save some money by not paying a shop. If anyone can shed some light on this post that would be great.
thanks!

"Painless wiring" setup

I've looked into them. I called them and asked if they have a universal harness and they told me the only way they could help me, was if I put a LS engine in..
