The temperature probe doesn't need any real installation- just plug it in and attach the sensor to whatever you want to measure, so very quick and easy. The voltage probe does need to be hard wired into the aircraft's electrical system. I decided to make a removable wiring harness so I could easily move the TM1000 and voltage probe from aircraft to aircraft.
Making a custom harness is very easy for anyone who is capable of soldering their own EC3 connectors.

Step 1: Cutting the wires

Step 2: Trim the insulation
Step 3: Soldering the connectors

You'll have to choose which end of the wiring harness you want your sensing wires to go. It doesn't matter if it's the battery end or the ESC end. Just take care to make sure your polarities are all correct, if they aren't you can easily fry your ESC, TM1000, battery, etc.
A third hand tool really comes in handy here. It's a bit tricky to solder both the power wire and the sensing wire into the connector at the same time. In the photo above you can see both wires inserted into the connector before soldering. I like to hold the soldering iron on the outside of the connector, wait for everything to get hot enough, then feed the solder into the joint. It also helps to put a bit of soldering flux on the wire tips.
Once the connector is soldered, press it into the EC3 plastic body. There are plenty of online videos / guides elsewhere to show how to do this in detail. Repeat for both wires.

Before I attached the connector to the other end, I chose to put a bit of heat shrink to act as a strain relief.
