Frequently Asked Questions - 99-8155 Metra

What vehicles is the Metra 99-8155 compatible with?

The Metra 99-8155 is specifically designed for 1997-2001 Lexus ES Series vehicles.

What tools are required for installation?

You will need a Phillips screwdriver, a small flat blade screwdriver, and a socket wrench.

Does the kit include a wiring harness?

No, the kit does not include a wiring harness. You need to use the factory harness or a separate adapter (Metra recommends using a proper mating adapter). Wiring connections follow the EIA color code.

What is the difference between DIN and ISO DIN provision?

DIN provision uses a metal cage to mount the radio, while ISO DIN provision uses brackets that attach directly to the radio. Both options include a pocket for storage.

How do I connect the wiring?

Strip wire ends 1/2 inch, twist matching colors together, solder, and tape. Use the EIA color code chart: Red (Ignition), Yellow (Battery), Black (Ground), etc. Isolate unused wires.

Do I need to disconnect the battery?

Yes, disconnect the negative battery terminal before starting installation to prevent accidental short circuits.

Can I install a double-DIN radio?

No, this kit is designed for single-DIN or ISO-DIN head units only. Double-DIN radios will not fit without modification.

What should I do if wires are unused?

Isolate and individually tape off the ends of any unused wires to prevent electrical short circuits.

How do I remove the factory radio?

Pry out the trim panel between ashtray and climate control, remove A/C vent assembly, unscrew four retaining screws holding the factory radio/climate control assembly, then remove the climate control from its bracket.

Where can I find the full installation instructions?

The full installation manual is available for free download on notice-facile.com or metraonline.com. It includes step-by-step diagrams.
