[. . . ] This will help avoid confusion when making connections later. Note: Do not connect the power connector to the stereo unit until you have made all connections. If there are no plastic caps on the stereo hooking wires, insulate all exposed leads with electrical tape until you are ready to use them. Identify the leads in the following order. Power Lead If your car has a radio or is pre-wired for one: Cut the connector wires one at a time from the plug (leaving the leads as long as possible) so that you can work with individual leads. If your car is not wired for an audio unit: Go to the fuse block and find the fuse port for the battery, usually marked BAT. Speakers Identify the car speaker leads. There are two leads for each speaker which are usually color coded. A handy way to identify the speaker leads and the speaker they are connected with is to test the leads using a 1. 5 V AA battery as follows. Hold one lead against one pole of the battery and stroke the other lead across the other pole. You will hear a scraping sound in one of the speakers if you are holding a speaker lead. If not, keep testing different lead combinations until you have located all the speaker leads. When you label them, include the speaker location for each. Antenna Motor If your car is equipped with an automatic power antenna, identify the car motor antenna lead by connecting one bulb tester lead to the car battery lead and touching the remaining exposed wires from the cut radio connector plug one at a time. You will hear the antenna motor activate when you touch the correct wire. Antenna The antenna lead is a thick, black wire with a metal plug at the end.
