Introduction / Preliminary

This premium installation kit is for 1988-03 Full Size Pickup/Sport Utility vehicles. Included are all the parts you need to mount your car stereo/cassette or CD player into your vehicle's dash. Refer to the individual instruction in this manual to remove your vehicle's factory radio and assemble the kit.

CAUTION:

Disconnect your vehicle's negative battery terminal before the installation to help prevent electrical damage. Scosche recommends the use of a Volt/Ohm meter over a test light to check wiring. A test light or grounded wire probe can cause damage to the vehicle's computer and/or diagnostic systems. Avoid all factory airbag wiring - airbags can accidentally deploy causing serious injury or death.

NOTES:

• See your vehicle's instructions for any special tools your installation might require.
• Read all instructions accompanying your car stereo/cassette player for proper wiring and mounting instructions.
