Hybrid is a better approach. Try a kit that has all the circuits you need plus a couple extra and then make all the new ends or tap into factory lighting harnesses. I used Kwikwire, they are like $300.00. It still ends up being quite custom. I know my car wouldn't be stick, the battery was going in the trunk with a relay, I was installing an under hood relay/fuse box for lights and HD accessories, radio was going in the glove box, MSD and coil in the car etc... http://www.kwikwire.com/wh_22Circuitstreetrodwiring.html
