Instructions
Follow these step-by-step instructions to properly wire your 2001 GMC Sierra radio:
Step 1: Disconnect the negative battery terminal
Before you begin wiring your radio, you must first disconnect the negative battery terminal to prevent any electrical shock or damage to your vehicle’s electrical system.
To disconnect the negative battery terminal, use a wrench to loosen the nut on the terminal and then remove the cable. Make sure to store the cable in a safe location away from the battery.
Step 2: Remove the factory radio
To install a new radio, you must first remove the factory radio from your 2001 GMC Sierra. To do this, you will need a screwdriver to remove any screws holding the radio in place.
Once the screws are removed, gently pull the radio out of the dash and disconnect any wiring connections from the back of the radio.
Step 3: Connect the wiring harness
After removing the factory radio, you will need to connect the wiring harness to the back of the new radio. To do this, simply match the colored wires on the harness to the corresponding colors on the back of the radio and connect them using butt connectors.
Make sure to wrap any exposed wires with electrical tape to prevent any potential electrical shorts.
Step 4: Connect the ground wire
The ground wire is typically black and must be connected to a metal part of the vehicle’s chassis. To do this, use a wire stripper to strip the end of the ground wire and then connect it to a metal screw or bolt using a butt connector.
Step 5: Connect the power wire
The power wire is typically red and must be connected to a switched power source, such as the ignition switch. To do this, use a wire stripper to strip the end of the power wire and then connect it to the appropriate wire on the vehicle’s wiring harness using a butt connector.
Make sure to use a test light to confirm that the wire is a switched power source before connecting the power wire to avoid any potential damage to your electrical system.
Step 6: Connect the speaker wires
The speaker wires are typically colored and must be connected to the corresponding speakers. To do this, simply match the colored wires on the wiring harness to the corresponding speaker wires and connect them using butt connectors.
Make sure to label each wire to prevent any confusion when connecting the wires to the appropriate speakers.
Step 7: Test the radio
After connecting all the wires, turn on the ignition switch to test the radio. If the radio does not turn on, check all the connections and make sure they are properly connected.
