If thereare no plastic caps on the stereo hooking wires,insulate all exposed leads with electrical tape untilyou are ready to use them. Identify the leads inthe 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 youcan work with individual leads.❐ Identify All LeadsTurn 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.Touch one wire at a time until you find the outletthat causes the test bulb to light.Now turn the ignition off and then on. If the bulbalso turns off and on, that outlet is the car powerlead.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 LeadIf your stereo unit has a yellow lead, you will needto locate the car’s battery lead. Otherwise you mayignore this procedure. (The yellow battery lead pro-vides continuous power to maintain a clock, memo-ry storage, or other function.)If your car has a radio or is pre-wired for one:With the ignition and headlights off, identify the carbattery lead by grounding one lead of the test bulbto the chassis and checking the remaining exposedwires 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 thebattery, usually marked BAT.SpeakersIdentify the car speaker leads. There are two leadsfor each speaker which are usually color coded.A handy way to identify the speaker leads and thespeaker they are connected with is to test the leadsusing a 1.5 V AA battery as follows.Hold one lead against one pole of the battery andstroke the other lead across the other pole. You willhear a scraping sound in one of the speakers if youare holding a speaker lead.If not, keep testing different lead combinations untilyou have located all the speaker leads. When youlabel them, include the speaker location for each.Antenna MotorIf your car is equipped with an automatic power an-tenna, identify the car motor antenna lead by con-necting one bulb tester lead to the car battery leadand touching the remaining exposed wires from thecut radio connector plug one at a time. You willhear the antenna motor activate when you touchthe correct wire.AntennaThe antenna lead is a thick, black wire with a metalplug at the end.❐ Connect All LeadsNow that you have identified all the wires in the car,you are ready to begin connecting them to thestereo unit wires. The wiring diagram (➡ page 58)shows the proper connections and color coding ofthe leads.We strongly recommend that you test the unit be-fore making a final installation.You can set the unit on the floor and make tempo-rary connections to test the unit. Use electrical tapeto cover all exposed wires.Important:≥ Connect the red power lead last, after you havemade and insulated all other connections.GroundConnect the black ground lead of the power con-nector to the metal car chassis.
