I'm installing an mtx remote starter in an 07 mustang tomorrow and will need to connect to the ebarake wire. When the audio guy had the car apart today I checked the wire at the lever today and the output wire has a low level ground on it even when the e-brake is off.
Any suggestions on how I will need to hook this up?
Thanks.

Did you check the voltage with the ignition ON or OFF ?

Ignition was off.

What exactly is a 'low level' ground? It's possible that the parking brake is a 5vdc system, but that is just a guess. ------------- Kevin Pierson

I only checked it with my test light (cts-1) yesterday, so I don't have a exact voltage. When it's a strong (12v) ground or positive, the led is full bright. The lower voltage the signal is, the dimmer the led is. The led was about 1/2 bright.

If your looking for somewhere to put the neutral safety switch, just ground it or put it to a toggle switch. Usually in a manual car the e-brake is always up.

Are you kidding? And what happens if it is not 'always up'? What happens when the owner leaves the vehicle in gear instead of using the parking brake? Not very good advice at all!
turboneon - Please do not follow this advice of just grounding the safety input! Always, use the proper connections and safety precautions. If the vehicle is a newer vehicle with an automatic transmission then grounding that input should not have any adverse effects on safety. However grounding it in a manual transmission vehicle does! ------------- Installer, IT support, and FFL. I need less hobbies.

My car, years ago, remote started while in gear with the parking brake on and still hit the car behind me (tranny was in reverse). You can NOT rely on the parking brake to stop the car from moving if it is remote started. ------------- Kevin Pierson

Thats why I suggested just grounding it or hooking it up to a toggle. It won't matter if he has it going to the e-brake or not...since the e-brake won't prevent the car from moving.

I think you missed the point. It's not safe so don't do it. It's not worth losing everything you own in a liability lawsuit. Get a unit designed for a manual transmission or a module that will adapt it to work with manual trannys. ------------- Kevin Pierson

manual safe remote starts are the safest way to go. If you let some1 borrow your car and they accidently left it in gear and remote started it, what happens then? it comes down to the personwho installed it and a huge lawsuit will be taken into place. this will only screw you up the rear. i suggest you DONT do wat 07 mentioned and connect the ebrake to a toggle. rather spend alittle more and get a manual tranny safe start.

maybe to late parkbrake RED / yellow at parking brake switch polarity - neg use a diode to isolate the parking brake switch from the BCM ------------- dragon

Don't worry. I only use the mtx designed units. When it comes to stuff like this, I act like everyone is part of the lowest common denominator club.

That's the wire I used, but I did not put a diode on it. Why would I need the diode? The unit has a specific e-brake input wire.
The unit I ended up using is a 2way rs/alarm from autostart.ca.
I have it completly installed, but of course, it still doesn't start. Locks/trunks/lights/alarm all work. It will do rs take over and accecpt the mtx reserve mode starting sequence, but when I hit the button to start it, the unit does nothing, no lights, no ignition, nothing. The hood/brake shut down inputs are all good and working properly.
Why is it my 1st year back doing these I end up with a bunch of cars with issues.

Did you get a bypass module for the chip in the key. I used dei's 556sw for my 07 mustang r/s alarm install.

I'm using an Autopage Key-override-sl module.

the reason you diode isolate is to prevent feeback onto the BCM. incase your unit sent out ground, it wouldnt short out the bcm.

Don't you mean incase the unit sent out a positive? If the unit sent out a ground into that circuit, it would be the same as the hand brake being applied.
As a side note, I finally got the car working properly. The problem was the wire I was using for the door triggers. The 2 different tech sheets I had had me using the what I came to find out was the dome wire for a door trigger. Once I found that out and found out the actual door triggers everything worked as it was supposed to.
