Adding Lines, Chassis to Door Options

[mr_dude]

So I'm doing a good quantity of interior LEDs and finally getting around to putting my power lock actuators in.

1. How have you all run your wiring ot the door? Just cut open the existing rubber tube and taped it back up?

2. I have to run 12 constant volts to the lock actuators. Where have you all put the actuators themselves, and gotten the 12v's?

Follow up:
After exhaustively trying each line for voltage and continuity with the 30A fuse socket, I partially removed the fuse box to find that the plug for that fuse box output had no line for the 30A slot.
I slotted some wire in there and got 12V with the 30A fuse, but the light was fading and I had to paddle out so I left it for tomorrow. Nevertheless, I'm optimistic this will power the actuators and not break the fuse.

But just be be sure, I don't need to put a resisitive load on the relays, right?
