❏ Identify All Leads The first step in installation is to identify all the car wires you'll use when hooking up your sound system. As you identify each wire, we suggest that you label it using masking tape and a permanent marker. 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. Turn the ignition on to the accessory position, and ground one lead of the test bulb to the chassis. Touch the other lead of the test bulb to each of the exposed wires from the cut radio connector plug. Touch one wire at a time until you find the outlet that causes the test bulb to light. Now turn the ignition off and then on. If the bulb also turns off and on, that outlet is the car power lead. If your car is not wired for an audio unit : Go to the fuse block and find the fuse port for radio (RADIO), accessory (ACC), or ignition (IGN). Battery Lead If your stereo unit has a yellow lead, you will need to locate the car's battery lead. Otherwise you may ignore this procedure. (The yellow battery lead provides continuous power to maintain a clock, memory storage, or other function.) E N G L If your car has a radio or is pre-wired for one: I S With the ignition and headlights off, identify the car H battery lead by grounding one lead of the test bulb to the chassis and checking the remaining exposed 214 wires from the cut radio connector plug. 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 will be two leads for each speaker, usually color coded. A handy way to identify the speaker leads and the speaker they connect with is to test the leads using a 1.5 volt 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 a speaker 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. CQ-VX2200W 33
