Hello,
What is the easiest way to wire up and install a dual/single electric fan setup to an existing EBL Flash? Im looking to install one soon and need to find all the information, materials and know hows before i pull the trigger and start buying relays.

Thanks!

The EBL Flash will only control one fan. If you go with duals there are several ways to wire it. If there is A/C in the vehicle that also needs to be taken into account. As the high speed or larger fan should run when the A/C is on. The EBL ECM operates the fan whenever the A/C is active.

A single fan is easy, just wire it as shown in the wiring diagrams.

For dual fans where both run at the same time, Casper's Electronics makes a dual relay set up that has a short delay built in. This staggers the turning on of the fans to prevent too much load all at once.

Can also place one fan under ECM control. Then use a head temperature switch for the other fan. Can also use the A/C request switch or an A/C head pressure switch in conjunction with the head temperature switch for the second fan.
