Power lock switch- passenger

[jcboy]

Hi, anyone knows where to wire up a power lock switch on the handbrake lever to?

The yarises here in thephilippines dont have that as part of the package nor does have it available at the dealer. (If its not in a stock car, its never available.like,say,a camry moonroof switch or something since camrys dont have moonroofs here)

Anyway im off to looking into japan importers for this switch theonly problem i have is where to hook.it up to. Cant seem to find it in the service manuals(either that or im still having problems understanding the electrical sections lol)

Thanks!
