❏ Required Tools You'll need a screwdriver, a 1.5 volt AA battery and the following: 12 V DC ELECTRICAL SIDE-CUT TEST BULB TAPE PLIERS 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. ❏ Dashboard Specifications THICKNESS MIN. 3/16" (4.75 mm) MAX. 7/32" (5.56 mm) 2-3/32" (53 mm) 7-5/32" (182mm) 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 vehicle power lead. If your vehicle 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). ❏ Identify All Leads The first step in installation is to identify all the vehicle 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 vehicle has a radio or is pre-wired for one: Battery Lead If your stereo unit has a yellow lead, you will need to locate the vehicle'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.) If your vehicle has a radio or is pre-wired for one: With the ignition and headlights off, identify the vehicle battery lead by grounding one lead of the test bulb to the chassis and checking the remaining exposed wires from the cut radio connector plug. If your vehicle 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 vehicle speaker leads. There will be two leads for each speaker, usually color coded. 20
