Am installing starter/alarm but don't know which of the drawings to go by for the locks-98 GMC Sierra - positive trigger / negative trigger , 5 wire alternating , two step positive or negative , too many options for a newbee. The first two diagrams use no relays , if the existing circutry allready employs relays areadditional relays needed? thanks for any help given Tony M. P.S. The unit is a Commando FM-870 two way remote start / alarm ------------- It's only broke,if you can't fix it.

5 wire (type C) on the two door models, and positive trigger (type A) on the four door and keyless entry models. POWER LOCK---------lt. blue @ either door boot
POWER UNLOCK---------white @ either door boot Type A is a (+) type door lock system where if you momentarily touch the target wire with a (+) pulse, it will activate the lock/unlock . Type C does the same with a (+) pulse but isolates the switch from seeing 12 volts to avoid possible damage to the switch. ------------- Jeff
