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 ?

What exactly is a 'low level' ground?

It's possible that the parking brake is a 5vdc system, but that is just a guess.

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!

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.

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.
