  1. You will be fine! It pops off but takes a bit of force. There is no sensor in the pillar and you would need to introduce a voltage to trigger it (or a spark actual on the explosive). 

    Taking it off and fixing any wires solidly is better, but you can actually get the cable down to behind the dash without taking the pillar cover off. Pull the door rubber off along the length of the pillar, which you have to anyway and shine a torch in. You will see the concertinaed light blue cloth of the air-curtain so will know where to drop the cable making sure it doesn't cross the curtain if it were to deploy.

  2. Haven't read through it properly but had a quick browse. I expect they are saying the same as me in respect of illumination - don't use the Lexus harness that goes to the existing radio, use one from an illuminated switch.

    They are talking rubbish about taking more of the dash apart - the speed sensor is on pin5 on the nav ecu and is white with a blue stripe. The parking brake is the yellow with red stripe on pin 17 of the nav ecu. The reverse is pin 14, Red with a black stripe on satnav ecu. you will see the harness going to the satnav screen with the radio out. That's the one to tap into.

    You can ground the parking brake if you want to yes. Don't ground the mute wire it will disable the audio and probably pause what is playing. Leave it disconnected and just tape up.

  3. The orange illumination wire needs to connect to a wire that goes live when your lights are on. It's used to dim the screen. You may not need it if the system has a built in light sensor. You can't take it of the existing Lexus harness as it gets it's signal from the instrument ECU and you wouldn't know what you might be back feeding. Best bet is to take it off one of the existing panel lights. The easiest will be one the seat heater switch backlights lights as you will have them disconnected already with the headunit out. I would try it without first as most detect the lighting levels in the car. Does the Android want an illumination input? Have you got the pinout for it?

    Blue wire for antenna remote goes live when you turn the system on to extend the antenna, or to power a radio signal amplifier. Unless you have one, that's not needed. Same with the other one labelled power control. If you want, you can use it to power anything else you want switching on when you turn the system on. (pretty low current though). Only one of the blue wires will work - it will be the one from the new stereo.

    Yep, you are right on the mute wire - you would only need that if you have something external to your system.

    I can't remember now, Has yours got the factory satnav in? Will you be using it or the Android one? Only because you will have to make another change or the satnav screen won't work, you have to fool it into thinking there is an original headunit.

    Are you fitting a reversing camera too?  Well worth it for the price they are.

  4. Yes, you are allowed to work on your own electrics without being registered. It must comply with Part P of regulations but nothing will happen to you if it doesn't. You obviously can't issue your own certificate of compliance. You would be responsible if it could be proven you caused a fire or left it in a state that would be dangerous though. It should be made legal like gas.

    It's so easy to burn your house down. Luckily this one had the distribution board in the garage.
