I am in mid stroke in re-building the rears for my truck and don't have time for elaboration on this project as of yet. I do plan on following up m ore on this for everyone interested but it will take some time.

As far as wiring diagram, the program has the pins etc. and info in it. All that is needed is to wire up the relays to the fan clutch ground wire through one relay (normally CLOSED) just like when installing a manual fan switch. For the compressor, I used the same on circuit that the cab controller used (normally OPEN relay). The triggers for the relays are going to the arduino. The pressure sensor I simply wired the sensing signal to one of the input pins (defined in the program) with a 50k ohm resistor in series and left the +5v and ground for it attached to the cab controller like it was. I only used the one wire from the pressure sensor to an analog in.

The project is unfinished by a long shot but very functional. I plan on making a better version, a better way to connect it, and better detail so that others can follow it properly but I just have not had time as of yet. Too busy re-building the rears and wiring of my truck, and that alone will likely take me a couple more weeks.

I hope you are working on rear ends with camera ON.
If not you are in trouble:big_smile2:
