I'm in the process of rewiring my mezeire electric water pump because originally, it was wired up really hokey. As I'm doing this, I noticed that there is an extra space for a relay in the fuses and relays box under the hood. I figure I may as well wire it there making the installation stock and clean. Has anyone else done this? If not, how come? I'm already running 1 wire through the loom that runs in front of the radiator, why not run 3?(I'll be taping into another source for the turn on lead.) Just curious. Any input or advise would be appreciated.
