Here you go. $30 in parts. You will need:
1 - generic Ford starter relay
2 - battery cable lugs (connects to the two large terminals on the relay)
Heat shrink tubing (seals and insulates the large relay connections)
14ga wire (length from Aux 3/4 wire next to the battery or to dash if separate switch) blue in diagram
Remove the negative battery connection, then the positive at the battery.
Mount the relay as close to the battery as possible (note which of the large terminals is for battery and which is for starter (winch)). Measure the length of cable require to reach from the large battery terminal on the relay to the battery. Ensure you consider safe routing and protection of this cable as it will be hot all the time. Cut this length from the red (positive) cable that runs from the winch to the positive battery terminal, measuring from the battery connection terminal end. Slide a 1 1/2” piece of heat shrink tubing over the cut end, properly attach one of the two lugs to the end and shrink the tubing to protect and insulate the lug connection (ensure the tubing does not cover the hole in the lug). Attach the lug to the large battery stud on the relay and then to the battery positive terminal (use the positive battery terminal mounting method provided with your winch).
Measure the remaining positive cable from the winch to the other large terminal on the relay, ensuring you route it safely through the engine compartment, avoiding sharp edges and objects and insulating, protecting the cable as required (this cable will only be hot when the Aux or separate switch is activated). Attach the other lug with heat shrink as described above and firmly connect it to the relay.
If you have the Aux switches, use either 3 or 4, the lug/heat shrink kit in the glove box and a length of 14ga wire to connect the small “S” terminal on the relay to the orange/pink (Aux 3) or dark blue/pink (Aux 4) wire next to the battery. If you don’t have Aux switches, you will need to mount a 15a minimum switch in the cabin with a fused B+ on one side and the small relay terminal on the other (if you use a lighted switch which I recommend so you know when it is on, run the third switch terminal to ground).
Attach the negative winch cable to the battery negative cable terminal and reattach the negative terminal.
See the rough schematic below. You are done, so enjoy!

Exactly the way my Warn interrupter is wired. Your method is definitely cheaper. I will add. The Warn switch includes all necessary terminals, wire, etc to install it. But either way it comes to choice. The Warn kit is twice the price of what you list in parts.
