  1. I would like to view the 2002 Toyota 4Runner Car Security Wire Guide. I am connecting a remote start with keyless entry. Thanks!

  2. I have a question regarding the power door lock wiring. I’m trying to install an alarm in my 04 4runner and cannot find the correct wires for lock/unlock. I found the plug that was stated as the correct one, but even after cutting the blue or green wires the lock still functioned. Anyone have suggestions?
