Notes:
*1 This vehicle uses grounds at the ignition switch to turn on relays and modules. To interface with the negative ignition wire to remote start, see directfax document #1500 for wiring information. This vehicle uses low-current, low-voltage switching in many places in the electrical system. Test wiring with a digital VOM. Do not use a test light.  *2 Relays located below right side dash. Remove panel to access. Lock module mounted vertically to right of relays. Small black plastic box.  *3 Diode-isolate dash end of wire. Sits at ground with ignition off.
