Electric Boot Release

I am back again.

 

It was this time last year when I kicked off the Project Elise Type R. A year on, I am still tinkering with it.

 

Next job, replacing my rusty boot release cable. Now, although you can buy the electric kits from various sources, due to the price, I opted to make my own.

 

Ingredients:

 

1. Christmas card ( for templating work)

2. Aluminium plate (for mounting)

3. Central locking actuator - 6Kg

4. Wiring

5. Relay

 

You should be able to get all the above for about £20.

 

Before I started any work, I had to decide the location of the button. There are several options in this, but the one that I thought to be best for what I was looking to do was to place the button on the door jam on the driver side. This would mean that the button could stay 'hot' at all times, but would require the door to be opened before gaining access.

 

The Build

 

Wiring harness.

 

This was pretty straight forward as its essentially two circuits, separated by a relay. One for the actuator and the other to the switch.

Mounting.

 

Now, I was initially going to use a bit of aluminium I have in the garage, however after a quick chat with a friend of mine, he was up to helping me out with fashioning something in his workshop.

 

So, by using a Christmas card, I templated my design and measured it up to ensure that the holes and shape worked as I anticipated.

Measuring up against the aluminium...

The making...

I am pretty happy with that!

Now, me being me, I couldn't just leave it there. I decided to add a power socket and an LED rechargeable torch for the boot and when you need to see in dark places sad.gif

 

So...

And...

Installation on to the car.

 

I had to remove the rear wheel and wheel arch liner to provide clear access to the route from the boot to the driver door side.

 

The speaker pod also needed removing by removing one screw and pulling off the velcro.

 

Drill the hole to the boot...

Removed the blanking plug to the cabin...

Masked the area to be drilled...

Pushed the cable for the switch through. Note the hard protective cover over the cable.

And a few minutes later....

Then installed the setup in the boot, including the isolating switch for the charger. I am quite happy with that.

So, the question is, does it work?

 

gallery_590_433_352766.jpg

 

Yes!!! sad.gif The pull is very positive and with no doubt that it would open the boot even if its a little stuck.

 

I am going to use the original cable as an emergency release, should anything go wrong with electrical system. Apart from that, I think I can call this a job done!! biggrin.gif

 

Quick update

 

It's been some time since I completed this mod, however it has taken me this long to find someone who would do a little logo for me to indicate where the boot release is.

 

So, thanks to Kosmo (Andy), he was able to get my exact requirements cut and sent out to me. I understand that he is pretty flexible and will be able to pretty much make anything to requirement.

 

I got it stuck on...

Hi, just seen this modification to the boot release you’ve done and what a good idea. I don’t yet have an Elise S1, but for sure all being well will do by the end of this month. What you’ve done here is something I’d also like to do. The light you’ve put in the boot, is it a light bulb or a rechargeable torch that you can take in and out?

 

Any help on where you got the live and earth from. Sorry more questions, what switch did you used at the doorjamb and for the boot release, where did the actuator come from or/and what make?

 

There are three more electrical modes I’d like to do to an Elise: I don’t plane on ever having a track day with the car so not bothers about extra weight. I’ll have to see when I get the car to see how achievable they are. The three things are: Electric mirrors, the Metro electric mirrors are selling for around £20 on the net.

 

Central locking, just don’t know how to get it to work with the alarm, so maybe now achievable.

 

And the third is electric windows, don’t yet know if there’s room in that door for a motor but if there is and get to know from what car the windows come from, then maybe an aftermarket motor will do the job

 

Thank you for any help you can give

Hey,

 

Good to hear from you. I bought the actuator from Maplins online. To be honest, you could use any door/ central locking actuator, just make sure that it has adequate power. The one I bought pulls at 6kg.

 

You can choose to go with a single circuit, activated by a single push switch, however I went with two circuits, one for switching and the other for power supply to the actuator. The two circuits are separated by a relay. It is very straight forward really.

 

I bought the push button on ebay.

 

Best of luck with your car and the intended mods.
