For the stock radiator I used the existing mounting bosses on the end tanks and made small brackets with thread inserts in them to mount the fan. For wiring, I just bought a pigtail for each motor and wire them each to their own 40 amp relay. They used a separate trigger using the Holley Terminator (160* F and 180* F) but I will be using the same trigger in the future (160* F) to get down to one output. If you're on a stock PCM you can use a thermostatic switch to operate the relay or there are some options for high-end fan controller like a Derale that offer a soft-start to decrease the initial amperage spike. I will say this upgrade was definitely worth it and they move way more air than my single 14" SPAL unit. Let me know if you if I need any specifics or help with yours.</p></blockquote><p></p>
