I bought a TK-104 GPS Tracker off eBay for £33.99. It includes a lot of features but the main ones I was interested in are:
- Shock alarm
- Geo-fence (alert if bike moves outside specified area)
- Continuous tracking (5 second intervals)
- iOS and Android App, as well as web interface
- Subscription only £2.79 a year, or free if you don't use online tracking (it has SMS and phone functionality instead)
- 60 days standby
- Engine cut-off
I mainly used Maddidog's 12v charge installation guide as a reference, but only removed the front windshield, grill and meter panel.
Step 1: Remove grills, windshield and meter panel - no need to repeat, instructions on Maddidog's guide linked above.
Step 2: Connect up engine cut-off. This is quite fiddly, you need to find the Brown/Yellow cable going into the ECU (below the ignition, down and to your left as you look inside the bike), this is the fuel pump, wire it up to the 12v relay included with your GPS tracker as per wiring diagram (may differ for different trackers, but for the TK104 the Red cable goes towards the ECU side and the Yellow cable goes towards the fuel pump). For reference, the full wiring diagram is on this post.Next, we need to disassemble some of the front end... Start by removing the fairing below the windshield by removing the two screws up in there:
And pry off the top area gently:
Unbolt the windshield:

Step 3: Wire up charging, I wired it to the lights so it would only charge while riding as per newpl's instructions here:
Step 4: Cable tie the slack and cable tie tracker to the frameSuccess!!!!!!! Plus is was easy and with minimal panels removed. Only remove 3 items!
So I wired it into the lighting system and it works perfectly. Power when the ignition is on.... and off when the engine is off. It's pulling around 5A with all the lights and engine on. With my phone, it's only 5.2A peak...plenty of cushion for the 10A fuse.
In case others want to do it, I tried to take pictures but since I did it in my garage at 10pm, the lighting is not good. Sorry for the bad picture. Basically, I used the connectors that maddiedog has in the post above and spliced into the Green(-) and Brown(+) wires.
1. Remove the front grill under the windshield from maddiedog's instructions
2. Remove the windshield from maddiedogs instructions
3. Pry the front meter panel (black plastic panel under the windshield. There no screws or bolts. Just the 4 holes that the plastic goes over)

Let's start with the easy wire... the Green. The same green wire goes to turn signals, horn, brake, license lights. I chose to use the left turn signal as it's easy to get to as it's right there.
The brown wire is much less common as it's only at the license light, fuse box, and into the dash. Luckily the dash is right in front of you. Pull the rubber casing down.
The brown cable is on the left bank of wires next to light green/black wire, the other side is 3 empty slots and the end is a white/blue

Step 5: Re-assemble!
The tracker comes with optional external antennas that are self adhesive. I stuck them to the inside of the windshield during reassembly.
Make sure to test connections along the way. If you trigger the engine cut-off it won't do much at idle as the PCX is so good on fuel, but once you've ridden 100 metres it will cut out if the tracker does it's job.
