Locating Tachometer Wire on 98 Tacoma

I've been trying to find this wire because of the purchase of a new car alarm/remote start. I've been told that it is a black wire behind the glove box. However, there seem to be several black wires and I'm not sure which one to choose. I'm not sure if I even have a tachometer wire since I dont have a tachometer gauge anyways...

Any input would be greatly appreciated.

Thanks

Tachometer wire is black and starts at the ignitor connector. You should be able to trace it from the ignitor to inside behind the dash.

I found it, Thanks a bunch
