Maybe I described the installation incorrectly. I have the large harness wired to the battery, and the secondary harness (with the lockers and isolation switch and lighting and ignition left out). I took the feed (red wire) that would have gone to the trigger switch) and connected it to the upfitter - since I did not get the modified instructions is there something here I missed, and if so, can you send that to me on PM? Tried to call, but you guys were already gone. Thanks!Yeah the updated instructions added a note for the single compressors that the wiring is different.
Looks like you are using a solenoid in your setup?
So the Single does pull 25.2 amps under load but I do not recommend you power it from your upfitter. Ford just didn't use a thick wire and in my opinion having them rated at 30 amps for the Aux1 is just not good in my opinion. I'd recommend using the supplied relay that came with your single compressor and using Aux 1-6 to trigger that relay. I just don't trust that small wiring Ford provided. Not sure why they rated it at 30 amps.
For 25 Amps going 6' you want a 12 AWG Wire. The yellow Aux1 wire is a 1.55mm (gee thanks for using normal measurements Ford!) wire. Which is basically 15-16AWG.
Sooo Fords not provided the proper wire AWG for the amperage they are rating it at.
Soooo i'd recommend using the included relay to power it directly from the battery, using the upfitters to trigger that relay.
On the twin it's easier, as the relays are already wired into the compressor, so you just need to trigger that purple wire.
