I have a 2005 Roadster base model. I have manual seats in them. I came across a deal and picked up a pair of power leather seats out of a limited.

I need to know the best way to get power to seat. There are two connections with 2 wires a piece in the floor under manual seat. The 14 gauge (red and brown) wire connector was not even connected to anything on manual seat. But less than 1v of power is in it. How do I get 12v under both seats?

The only way I know offhand is running a wire through the firewall and fusing it with an online 30a fuse at the battery. Is there an easier way?

Thanks!
Matt
