Don't know why you went to all the trouble feeding through into the engine compartment, there's a perfectly good fuse board in the cabin, and this had both permanent live and switched live feeds.

Most he'd units have a permanent live to retain the memory, and switched live to power them off with the key. Didn't the installation instructions tell you this?
