Where is this exactly? Trying to check fuses/relays/modules to resolve a parasitic battery drain problem. Inquired a couple repair databases already. Neither states a specific location - they just mention the controlled power relay in terms of what it does. Thanks in advance.

Your owners manual should explain about the location of all fuses and relays.

I think that relay might be under the driver's side door sill moulding. (towards the front).

It may be easier to just remove the fuse that's feeding power to that relay and see if the parasitic drain goes away. 

MaxiFuses/Relay Center

The MaxiFuses and relays are located next to the engine
compartment fuse block on the driver’s side of the
engine. To access the compartment fuse block, remove the shroud cover.

So if you pull that Body 3 fuse and the parasitic drain persists you know it isn't because of the Controlled Power Relay (or anything else on the "Usage" List).

But if you pull that Body 3 fuse and the parasitic drain goes away, then the Controlled Power Relay (and everything else on the "Usage" list) needs to be checked
