I have a very bad habit of leaving my lights on with my autostarter. Because the autostarter keeps the car running until all my doors are closed, the light “alert” doesn’t beep me.
I’m going to try to fix this by wiring the alert to alert me whenever the door is open (car on or off) and when the light is on.
Now, my question is: if I were to cut the “ignition” wire (the wire that is detecting my car is on/off to the alarm) and leave it will this affect that more than just that circuit?
The wording is hard to work out. Basically, if the wire is “off” (indicating my car is off at all times to the alert) would this have an adverse effect on any other alert?
This alert only works with the head light switch. I don’t remember hearing it at any other time.
Has anyone tried something like this? I’m going to do some exploring and find the “noise maker” but I suspect it’s not going to be as easy as cutting one wire.
OK IF I understand what you are suggesting, I think that the lights on alert will sound all the time, not just when the door is open.
Whithout a wiring diagram for your exact car, there is no way I can tell you how to wire it.
It might be easier to wire the headlight relay to a switched ignition source so that the lights will only come on when the key is on. (FYI European cars have been wired this way for 30 years or so.)
Well, I’m trying to make this as simple as possible.
The light switch idea could work. Would splicing the two wires (the hot light switch wire and the ignition position switch) work? Or are there easier ways?
I don’t have a wiring diagram for my car (2003 Toyota Matrix) and I’ve been googling for anything but I’ve come up empty.
All I can do is check each wire and find the ones I need (using deduction and a circuit checker). Would a simple diagram be labeled anywhere?
Why not just buy the factory electrical manual? I have no idea how much Toyota charges for it, but for any car I’ve owned it’s been in the range of $10 to $30. Typically these contain a page or two for each electrical device on the car. More information than you’ll ever need, but invaluable if you (or your mechanic) are trying to trace a fault.
