Installation Guide (Continued) ❏ Identify All Leads The first step in installation is to identify all the car wiresyou’ll use when hooking up your sound system.As you identify each wire, we suggest that you label itusing masking tape and a permanent marker. This willhelp avoid confusion when making connections later.Note: Do not connect the power connector to the stereounit until you have made all connections. If there are noplastic caps on the stereo hooking wires, insulate allexposed leads with electrical tape until you are ready touse them. Identify the leads in the following order.Power LeadIf 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 canwork with individual leads.Turn the ignition on to the accessory position, andground one lead of the test bulb to the chassis. Touch the other lead of the test bulb to each of theexposed wires from the cut radio connector plug. Touchone wire at a time until you find the outlet that causesthe test bulb to light.Now turn the ignition off and then on. If the bulb alsoturns off and on, that outlet is the car power lead.If your car is not wired for an audio unit: Go to the fuseblock and find the fuse port for radio (RADIO), accesso-ry (ACC), or ignition (IGN).Battery LeadIf your stereo unit has a yellow lead, you will need tolocate the car’s battery lead. Otherwise you may ignorethis procedure. (The yellow battery lead provides contin-uous power to maintain a clock, memory storage, orother function.)If your car has a radio or is pre-wired for one: With the ignition and headlights off, identify the car bat-tery lead by grounding one lead of the test bulb to thechassis and checking the remaining exposed wires fromthe 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 bat-tery, usually marked BAT.SpeakersIdentify the car speaker leads. There are two leads foreach speaker which are usually color coded.A handy way to identify the speaker leads and the speak-er they are connected with is to test the leads using a1.5 V AA battery as follows.Hold one lead against one pole of the battery and strokethe other lead across the other pole. You will hear ascraping sound in one of the speakers if you are holdinga speaker lead.If not, keep testing different lead combinations until youhave located all the speaker leads. When you label them,include the speaker location for each.AntennaThe antenna lead is a thick, black wire with a metal plugat the end. ❏ Connect All Leads Now that you have identified all the wires in the car, youare ready to begin connecting them to the stereo unitwires. The wiring diagram (➡ page 25) shows the prop-er connections and color coding of the leads.We strongly recommend that you test the unit beforemaking a final installation.You can set the unit on the floor and make temporaryconnections to test the unit. Use electrical tape to coverall exposed wires.GroundConnect the black ground lead of the power connectorto the metal car chassis.Important: Connect the red power lead last, afteryou have made and insulated all other connections.23 CQ-RG153U
