I'm half way done with Willie's Total Fan Control. I just need to finish the Hayden 3647. Anyone who has done this please help answer me this question. I may be over thinking this... In the instructions, ******* says:

"In addition to the Hayden 3647 kit, an additional automotive 12-volt, 30 amp SPDT relay is required (using the one from the Hayden 3652 kit). The other relay will have the terminals labeled:
30,
85,
86,
87 & 87a, or
87 & 87
Wire the Hayden unit as per instructions with one difference: Connect the Fan (+) wire to #86 on the SPDT relay. The other relay connections are wired this way:

#85 to ground
#87 to ground.

Splice (tee) a new 18-gauge wire into the green/white (or gray) wire at the existing fan relay and connect this wire to #30 on the SPDDT relay. Leave the center terminal on the SPDT (#87a or a second #87) unconnected.

One question is in red bold. The "Fan (+) wire is to #86 on the SPDT relay". Is this wire, the wire actually go to the existing secondary fan motor? The 8647 relay has two wires, blue and orange, which the diagram says should go to the fans. Am I leaving blue and orange unconnected?

Also the 3652 relay and the Hayden 8647 have a red "Power Supply" wires that in the diagrams go direct to the (+) on the battery. Is this correct?

Also the both have a yellow wire that the diagram says to connect to a 12-volt connection that is controlled by the ignition. What happens here?

Does anyone have a diagram of how the Hayden 3647 is hooked up, telling me what goes where? This help will be greatly appreciated. I look forward to sharing some pictures too of my custom made switch box with leds when I'm all done.


Thanks.

Oscar.
