If you still need help with this, I did a write up long ago that you may be able to find. I just did the add a fuse and also put in a switch for them, this made sure I didn't have to splice anything. I left the switch loose in the fusebox, as I didn't want to drill into the dash, but it sits in there fine. This allows you to atleast turn them off/on at your desire. Its easy to hide the wires using the center console and on the back seats, some velcro works wonders and stick it to the hump in the carpet where the floor vent is under the front seat. For the front lights, I just used some 3M Double Sideded Adhesive Tape. I've had mine in for 2+ years now and no issues falling down or anything.
