      How To Wire DCC Controller with Trinary switch

      Hey guys I’m so horrible at wiring! Just got my DCC fan controller and I really don’t get the instructions.

      1. Am I supposed to wire the fan controller directly to battery positive or negative? Or can I use starter solenoid or alternator as battery positive and core support as negative?

      2. How do I wire the Restomod Air Trinary to the controller? A diagram would be super helpful!

      3. According to Restomod Air diagram, white wire from compressor relay goes to Trinary switch. Do I have to run this white wire from interior to exterior via grommet? Or can I use one of the inputs of the AAW wire harness?

      4. According to Restomod Air the red/white wire (08) and red wire (32) gets +20vdc. Is this correct? Or a misprint? Where will I get +20v from?

      Here is a link to the DCC instructions:

      Hi Joe. I embedded answers below. Hope this makes sense.

      I take the positive right to the battery (or the firewall bulkhead if trunk mounted battery) and the ground to the engine block.

      2. How do I wire the Restomod Air Trinary to the controller? A diagram would be super helpful!

      One of the blue wires of the trinary switch to 12 volts, the other blue wire to the blue DCC AC input wire. The trinary switch black wires are connected as shown in the Restomod wiring diagram.

      3. According to Restomod Air diagram, white wire from compressor relay goes to Trinary switch. Do I have to run this white wire from interior to exterior via grommet? Or can I use one of the inputs of the AAW wire harness?

      Personally I run it through a grommet. Iím a simple man and like to keep things simple. Plus I have a bad memory and wonít remember what I did if I do something fancy and I have to troubleshoot later.

      4. According to Restomod Air the red/white wire (08) and red wire (32) gets +20vdc. Is this correct? Or a misprint? Where will I get +20v from?

      That has to be an error. It should be 12 volts.

      Thanks Don!

      I’m not going to have a firewall bulkhead for a cleaner look. Can I run the power wire to the alternator? The DCC website has some filter if running power to alternator/starter is that needed? If I had a bulkhead connector essentially that’s same as running directly to starter or alternator. Everything is interconnected anyway right?

      The DCC ac trigger has 2 wires a blue and green, blue I run to trinary as you said and green isn’t used? What’s it for then?

      Lastly, the wires coming from the trinary are super thin, the wire from the compressor is much thicker, will that thin trinary wire be enough?

      I would not connect it to the alternator or starter without the added DCC filter. Alternator outputs can be quite dirty with spikes and noise. Starters can generate large spikes.

      The DCC ac trigger has 2 wires a blue and green, blue I run to trinary as you said and green isnít used? Whatís it for then?

      Not sure what the green is for, perhaps a ground trigger. If itís not called out in the instructions, donít worry about it. Or maybe send an email to Brian since he seems to respond to you... :>)

      Lastly, the wires coming from the trinary are super thin, the wire from the compressor is much thicker, will that thin trinary wire be enough?

      Should be fine.
