accessory, keysense definitions?

I am getting ready to hook up an alram and have read my wiring diagram but am unsure of what thes things exaclty DO and if any1 could shed some light.

ACCESSORY

SECOND ACCESSORAY

KEYSENSE

THNX

First thing....year make and model. You can find definitions for these terms  I see in your sig, Ford Ranger, what year?

Accs, gets "hot" when the key is in the accs posistion, and energizes things like the radio, in some cars the locks, and heater or AC

Second accs.    sometimes there is more than one circuit needed to take care of all the accesories in the vehicle, depends on the vehicle.

The keysence is in the ignition harnes or near the steering column. Think about the word. sencing the key ....in the ignition. some cars it disarms factory security, allows the door locks to function by waking up the BCM.....etc.

If this is your first install of a remote start....get some help and be careful.   We will try and help you, but there is only so much we can do for you over the interweb.....

The THNX....? I have no clue

AND, I dig your screen name....
