you mean a constant wire? get a test light and check under your steering column for a 12V constant wire.

If you want to risk blowing your airbag, get a test light. If you want to do it right, use a digital multimeter.

If you want to hook up a scanner to an aftermarket alarm you need to find the ground when armed output on your alarm brain. All DEI brains use an ORANGE wire for this feature.
