The fan and adapter that tminer listed make it plug and play so that both fans run on high whenever the ecm commands the fans to turn on. However, the stock high speed options are lost (delay relay, ac line pressure, and overtemp switch on the manifold) because if you look at the adapter ramchargers only uses two of the three pins. If you add the middle pin and two wires from that pin, one to each of the red wires on the end pin, the fan will also run off the high speed relays. That's nice because the fan switch that most guys add for staging lane cooldown is tapped into the overtemp switch and does not function with the ramchargers setup. Yes, this mod makes the fans run on high speed whenever they are on, but is much simpler than the extra diodes and relays to get true high/low speed operation. Oh, don't ask me where to get the pin - I've been told it's very hard to find. My plan when my stock fan eventually dies and I install the ramcharger fan now gathering dust in the garage is the steal a pin from the stock fan

. Finally, electrically they are plug and play, but you have to fabricate mounting tabs to get them installed. Use some 1" x 1/8" flatbar in your favorite flavor (aluminum, galvanized steel, old rusty iron, whatever

), drill holes in the shroud, and use the flatbar to connect the hole with the stock mounting studs. About 3-5" per mount, if I recall correctly, or 1 to 2 feet total? Also, the mount tabs on the sides are not needed so most guys cut them off for extra clearance. Try to get the shroud to wedge in between the end tanks for maximum rigidity and to minimize the air leakage, or stand it off and use some weatherstripping or edging if you like. I think The Source is going to do an article on all this in the next issue, if you want pictures.
