Inkbird Hardwire Help

[sremed60]

Most of the wiring tips I've found are for wiring two electric outlets into the unit and plugging a heater into one and a cooling device into the other. The refrigerator I have has the power cord going into the compressor. Then it has (1) yellow wire, (1) gray wire, and the green/yellow grnd going to the OEM thermostat.

If it's possible I'd like to just replace the OEM thermostat with the inkbird, leaving everything wired as is and just taking those 3 wires off the OEM and plugging them into the Inkbird.

Based on what I've read it sounds like it's possible, but I haven't been able to find anything that specifically addresses exactly what I want to do. Hoping someone might be able to point me to a wiring diagram to help? Attached is a pic of the thermostat and the compressor I have.

Actually, there have been quite a few similar threads lately.
In any case...

- leave the green/yellow wire where it is.
- remove the yellow and gray wires from the oem thermostat and connect them to the two terminals of the Cooling relay (7 & 8) in either order.
- wire the power supply pins (1 & 2) to the hot and neutral leads from the incoming line cord.

It's actually that simple...

Cheers!

I appreciate the help. I'm not the brightest knife in the drawer - I followed you up until:

wire the power supply pins (1 & 2) to the hot and neutral leads from the incoming line cord

That's where my brain went off the rails.

I took some more detailed pics to show what I have. The first pic is the incoming 3 wire line from the plug. The center wire is ground. The wire to the left is black with white writing and the wire to the right is black with a white stripe. I've always seen a solid black wire for neutral and then a black wire with either white writing or a white stripe for hot? So I'm not sure which is which.

The black wire with white letters gets connected to the yellow wire with this thing? I'm not sure if this is a different kind of wire nut that I've not seen, or if that white plastic thing is some kind of resistor or capacitor or something?

The black wire with the white stripe plugs into the bottom of the compressor, (the green cap in the pic).

The gray wire coming out of the top of the compressor went to the thermostat along with the yellow wire.

You said to just leave the green/yellow wire on the OEM thermostat where it is. It just went from the OEM thermostat to a mounting screw on a bracket, (shown in the pic below). Since I am totally bypassing the OEM thermostat there's no reason to leave that wire on it? I've already cut the old OEM thermostat off so now that green/yellow wire doesn't connect to anything but the bracket?

So based on this, can you tell me which wire on the incoming line is hot and which is neutral? The green wire from the plug is just screwed on to the base of the compressor - can I ground the Inkbird to the same screw?

Thanks in advance

Cheers

The black wire with the white letters that is connected to the yellow wire is your incoming AC hot lead.
You can actually daisy-chain that wire to pins 1 and 7 of the controller.

The black wire with the stripes that is connected to the compressor is the neutral return and should be wired to pin 2 of the controller.

The green wire is safety ground and should have been left intact.
Find some solid place to connect it to the chassis...

Cheers!

Can you post a pic of the final wiring on the back of the STC?
