theres one that how to markVIII your obs on a budget you can go that route. otherwise you can buy a sensor reliant controller on jegs/summit. im going to use ls1 fans with a jegs harness. ill have one fan controlled by the sensor and probably have one relayed so itll turn on when its over a certain temp or ill put it on a switch as an override fan.
-you wont need a tune unless you do a PCM controlled fan, which theres kits for also.
-not hard to wire in the sensors are either probes or threaded into your head. i cant seem to get the plug out of the way because of my headers otherwise i wouldve done mine already.
-vehices to l ook for. some people use taurus, jeep, markVIII, lt1, ls1 etc etc. my theory if its from a v8 it can cool a v8. careful as some fans are dual speed like the markVIII which require differnt wiring like his thread shows if you want it to work as intended. otherwise many are just two wire. power and ground, you can hook them straight to your battery with a fuse, relay and switch if you felt like it, but thats a hack job IMO.
- no need to reroute pulleys, just run the wiring for the fans down the firewall, ziptie or loom them all together and keep them out of the way. you will have to figure out a bracket system for your fans and that is about it.
