multiple lights, wiring

First of all, I'm a newbie at wiring and such, so please excuse any stupid questions/actions. I hooked up two neon tubes, 2 LED tubes, 6 single LEDs, and 3 wire lights through the firewall to my battery with a fuse on the positive and a switch on the negative. However, only the single LED's lit up... So I split the wires into four groups, with 4 wires running to the postive end of the battery; however it seems like I will need to run 4 wires to the negative end of the battery too?!! Is there anyway to prevent this because 4 switches would just look silly =P PLEASE HELP ANY WAY POSSIBLE... diagrams would be nice ;)Working on the car :)

Oh yeah, I forgot to mention that I did wire them in parallel circuitry Working on the car :)
