I need to wire up some electric fans, but need to do it before I can get a controller in the mail.... Like tonight. Assuming I was to use a manual switch to temporarily control the relay, where in the engine bay could I tie in to? Or my understanding of relays wrong and in that case, feel free to lash me verbally. Any help is appreciated. The car runs and drives well, but absolutely hated the gridlock this morning. I need to move more air at low to no speed.
