You will be ok, I've installed a lot of them. A relay and a solinoid are the same thing. Bolth use an electromagnet to pull in a set of contacts (hence forth the click)conecting your power source, which should be your battery. or you may have conected it too the in side of your "power distrubution block" as I've named it (same thing as the battery). The draw of power the little electro magnet takes is minimal. and as long as you installed the in line fuse that should have come with the kit you should be Ok. You wont see any affects.
