2009 toyota corolla add on starter

Need help finding wire that gives negative or positive output when lock button is pressed on factory remote. Add-on(mars 10) is installed and working if i manually give 4 ground impulses, only thing left is finding wire to hook up. Wire that triggers door lock wont work because its dead when remote button is pressed.Any suggestion is appreciated. Thank You.

No remote does not work after car is running, I`m aware of that and its OK. Key will have to be used to enter vehicle and shut it down if needed.

That is the one i was trying to use. If i use that one i can start vehicle pressing lock 4 times on the doors but not with remote.

You want to use the wire listed as "lock motor" on most tech sheets. This wire will shows +12v when locking with the remote or switch on the door. According to the link below it is BROWN or ORANGE depending on the model of Corolla you have. You can find the wire in the drivers kick panel. You may need to use a relay to switch the polarity if your unit requires a (-) signal. https://www.the12volt.com/installbay/forum_posts.asp~TID~102124

Come to think of it you will need relay driven lock outputs from your unit, you have to open the lock wire. Also and I'm asking not telling, isn't there a key-sense wire one could use?

There is(blue @ignition switch), but how would i use keysense wire to neg. impulse? Or maybe i did not understand what you mean.

Listen to what Jworm has posted, it's the correct way to do this. The wire is in the harness coming in from the drivers door...Mike M2
