More info please or a guide fancy doing this to mine
Didn't take photo's but can give you a list of what to do:
1: Get a Velleman VM130 from Maplin, these come with a 2 button remote and 2 relays in the control box. The reason I went for this model is it has a variable timer, I have set min to 15 minutes. It also has a built in heater so it still works in low temperatures. Get some wire to suit I purchased 2m of black and red automotive cable from Maplins at the same time. I need to fit an inline fuse but they had none in stock.
2: Unclip near side wheel arch liner, you only need enough clearance to allow access to the multiplug on the FBH, once you can get to it unclip the multiplug so you can splice the red wire into the wire going in to pin 3 on the multiplug.
3: Plug it back in and follow the existing cabling up to the rubber grommet, push this out and feed through the cable you have ran following the existing loom. Leave plenty of excess.
4: Drill a hole in the front top right (as you're looking at it from the front) box with the ECU in it, hole needs to accommodate 3 wires.
5: **Disconnect Battery before this step** Run a red wire to the +ve battery connection and a black cable to the -ve an feed through the hole in the ECU box.
6: Connect the +ve and -ve wire to the power terminal block on the remote control box, you will also need to run a short length from the +ve terminal to the com terminal on the relay. Then connect the wire from the FBH to the normally open terminal on the relay.
7: Put everything back together and cable tie where necessary.
8: Test it works by pressing the button on the remote fob, you should hear the FBH kick in to life.
Job done. If you blow yourself or you car up I'm not liable...
Looks complex but took me less than an hour, biggest ball ache was cutting the heads off the screws holding the arch liner in place.
