Permanent 12v Dash Supply for Remote Boot Release
Discussion
If you take the live from the interior light delay relay you'll find the supply terminal should only be live when the car has been unlocked, test with a meter to confirm you have the correct terminal.
This is ideal for a hidden external boot release switch like the badge one on a Cerbera as it'll be disabled when you lock & leave the car, you could even take it from the interior light itself, IIRC it's a purple wire but again a quick check with a meter will confirm this.
Thinking about it, if you have a later car with mirror mounted door release buttons taking your live from that circuit would be equally effective.

The buttons are still live when the car is locked (you can hear the solenoid operating, but the lock holds the door closed), so it wouldn't achieve the same effect.Dr Mike Oxgreen said:

What I can tell you without any doubt is that the interior light only becomes live once you've unlocked the car, as I said before I think it's the purple wire from memory.
Any way, once you've wired your boot release switch to the interior light feed you can only use it after you've unlocked the car, I fitted a magnetic reed switch like model railway hobbyists use to switch points on the track when the train passes it.
Wire this little magnetically activated (normally open type) switch to the interior light circuit and fit it invisibly behind the numberplate, all you then need is a tiny magnet in your leather key fob which you pass over the known spot on your numberplate and the boot pops open.
Here's the switch I used, I chose it because it's sealed, you get the magnet included and the pack comes with 3 switches, so share with your friends

Buy the pack of 3 switches and the magnet here for less than £10 including postage:

This system has proved 100% reliable and makes accessing the boot a breeze compared with the stupid "key on" press the under dash button system TVR gave us.
Although I should point out my under dash button still works too if I need to pop the boot from the drivers seat, this is actually quite handy when I'm picking up the wife after one of her many shopping trips as it means I don't even need to get out to open the boot for her

I have to say my model railway magnetic reed switch boot opener is one of the best little mods I've done to the car, makes life so much easier

Choo Chooo went the TVR nerd!!!!
