Fitting tracker to vehicle.

Is there a fuse purely for the starter motor?

Yeah. Under the bonnet. Thats why I'm thinking it should be as easy and chopping into that positive wire and putting the relay there as it shouldn't mess with anything.

Ok I'll try those, but just thought they would be mainly owners rather than tech experts.

A few years ago I'd have just given it a try, but I'd be more cautious these days. You'll find a lot of technical info on some of the car forums - give them a try.

Be interested to know the outcome.

I'm assuming from the "push button start" comment your vehicle has keyless entry and or ignition if so I would be more concerned in securing the OBD port to prevent thieves being able to program a new key / fob

Yeah it is. I couldn't see the ODB when I looked briefly but will keep going. Thats why I want this start motor relay cut out because then even if they program a new key, it won't start because I can disable it independently from the cars computers.

It will definitely have an ODB port. Almost certainly under the dashboard near the steering wheel I would have thought.

Does this vehicle have the stop / start function when stopped in traffic

Does this vehicle have the stop / start function when stopped in traffic

No it don't. Which I think would have been better because it meant that if it got stolen, the first time it stopped it wouldn't turn back on again

What I'm thinking now is connecting the relay to the start button. The button has 4 wires (from what I saw on the web) Of which I am assuming are:
1. +'ve for the internal LED
2. -'ve for the internal LED
3. +'ve waiting to be used to send signal
4. the switched live that gets pulsed when the button is pushed.

Wire 4 only has two states, on and off so having a relay in there which is turned off is no different to the button not being pushed. It will just block the current/signal to the computer telling it to start the engine.

Thoughts?

Nope. That’s wrong. I’ve revised my thinking.
1. 12v +
2. GND
3. ACC line
4. Starter line

This demonstrates how shallow your knowledge is of vehicles using this technology, until you manually stop the engine it remains active

I don’t know what “remains active” is supposed to mean, or what effect it would have.
What I do know, is you need to tone it down.
The OP has asked for advice.
If you don’t want to give any, then don’t.
There’s no need to be insulting.

So you’re telling me that if I connect the relay in front of the starter motor, someone steals it and the tracker notifies me, I press the button to throw the relay cutting power to the start motor, the engine won’t cut out immediately (because that’s illegal) but the next time they stop the car and the engine stops with it, the starter motor isn’t used to restart the engine? Is that what you’re saying? The starter motor is ONLY used when you first push the button to start the engine?

Thank you spinlondon. I get fed up with these forums sometimes. Every forum has people like this. Don’t actually want to help anyone, just ridicule them.

Sounds like you have jumped into a thread without reading through it

I think from some of your replies in other threads you need to take some of your own advice

So you’re telling me that if I connect the relay in front of the starter motor, someone steals it and the tracker notifies me, I press the button to throw the relay cutting power to the start motor, the engine won’t cut out immediately (because that’s illegal) but the next time they stop the car and the engine stops with it, the starter motor isn’t used to restart the engine? Is that what you’re saying? The starter motor is ONLY used when you first push the button to start the engine?

The stop start system once the engine is started is operated from the ECU not the button on the dash until the button is pressed to stop the engine and it is then deactivated

You are making an assumption the the start button has a direct connection to the starter motor this is not a latching button

Clearly the advice I've offered does not meet your expectations or has been misinterpreted, I don't know your level of competence or what tooling and test equipment you have available to you, what I do know is they are complex vehicles that need a different approach to the one your have.
If you are considering continuing with this mod and "brick the vehicle" it will turn a cheap mod into a very expensive *****
Trying to run a modern Land Rover on a shoestring budget isn't an easy thing to do and most of the people I know doing it have access to at least their own diagnostic equipment
On that note I have taken your advice, you have been assigned to room 101 along with another contributor to this thread

Ironically I think our ‘wires have been crossed’ (don’t trip over that pun)

I was talking about if I was going to put it in front of the starter motor as obviously the starter motor will turn every time. Yes I agree that the button won’t have the same effect.

Other than the belittling yes your contributions have been some what helpful. I know these are complex machines but what I am looking to do is not. I don’t intend to intercept a data line. From my understanding of it is that when you push the button it sends an electrical signal to the computer telling it to start. If I close the relay it was stop that signal from being able to get to the computer. Which is exactly the same as just not pushing the button. I can’t understand how this is so complex and would damage anything. It’s either sending pulse voltage or not.

I’m not saying you’re wrong, but fitting it this way, can you explain how this could be damaging to anything and what could go wrong? (Assuming I’ve metered and found the right cable) I can’t see that putting a closed relay is any different to not pushing the button.
With the relay closed if a thief pressed the button that signal would simply just not reach the computer, same as before he pressed the button. No?

I don't know your level of competence or what tooling and test equipment you have available to you,

I have a multimeter, soldering iron and a can-do attitude. Is that enough?
