Things you will need:
Timer kitset
Box to put it in
Some heavy duty wire
Soldering iron and solder
Heat sink clamps (highly recommended)
Electrical tape
Jaycar book (optional but recommended, makes instruction easier to read)
Craft knife
Wire cutters/crimpers
Multimeter (optional, not needed if you use the wires I mention)

The kit itself was fairly easy to put together, total assembly time was around one and a half hours. If you've never put together a kit set it might be a good idea to get someone good with electronics to give you a hand as soldering can be a bit fiddily. Once it's all together you set the maximum time you want the timer to go for by setting the rotary switch, I set mine to 5 minutes. In order to get to the maximum time you must of exceded the threshold (more on that later) for 25% of the last 7 minutes you were driving. Put your timer into its box but don't put the lid on yet.

Now that your kit is all completed it's time to wire it into the car. First off, disconnect the negative battery terminal. It is fairly easy to wire up, with only four wires needed to make it go. The first wire we will do is the boost sensor output wire which you need to get from the ecu. Take off the kick panel and the panel under the glovebox as well as the two plastic bits that run down by the door sill. The wire you want is number A-17, it is a yellow wire. Connector A is the larger of the two and the one that is further back and harder to get at. Unplug that and look down at the top of the connector where the wires are going into it. Number 17 is the one on the bottom right, the yellow one. Tap some wire into that and solder it up then run it to where your timer is and screw it into the sensor input connector. Don't forget to cover the connection in electrical tape.

Next up is the earth wire, this is pretty simple so you shouldn't have any problems with that, there are earth's everywhere. Now we need the two ignition wires. Take off the plastic ignition switch cover then undo the reuseable zip ties holding down the wiring. Get out your craft knife and cut off the shrink wrap covering over the ignition wires. You need to tap in to two of the wires here, the constant 12v wire and the ON wire. The constant 12V is the big black wire and the ON wire is the black wire with the white stripe. Tap your heavy duty wire into those two then solder it up and rewrap with electical tape. Now you need to connect the two crimp joiners onto the end of each bit of heavy duty wire and push those onto the crimp connectors on the timer.

Your timer is now ready to go, double check all your connections then reconnect the negative terminal.Now you need to tune the timer so it knows when your boosting. Turn the ignition to ON but don't start the engine. You need to turn the little screw thingy anti-clockwise until the LED comes on. It takes around 10-15 full turns to get it to come on, although this may vary a lot. Once the LED is on slowly turn it clockwise until it goes off again. Now your timer is set so it will come on when you boost aproximately 2-3psi. You can tune it to higher levels by going for a drive with a mate up a long steepish hill in a high gear. Get the boost to aprox where you want it to trigger the timer and then get your mate to turn the screw clockwise until the LED comes on.

Right so now it is all tuned start your car, give it 10 seconds or so to run and then turn it to OFF. The car should turn off. Good, now take the car for a good thrash (after its warmed up of course) then turn it off again, it should stay running for a few minutes. Once your happy that it works fine put all the interior panels back on and put the lid on the timer box.

Conclusion.
I think this thing is great, it is less then half the cost of an equivalent "intelligent" turbo timer and works perfectly. It was very easy to build, setup and install. Not much else to say really, after all it is only a turbo timer, as long as it does its job theres no problems.

Next up will be a review of the jaycar boost controller.
