Hi Metch,

Välkommen to the Brickboard!!!!

Snow? Motor safely, please!!

RX-93UK! Thank you.

The RX-93 UK offers AM, FM stereo, and an auto / manual reverse stereo cassette tape transport mechanism. RX-93UK uses a bolt-on integrated amplifier secured to the back of the chassis. The amplifier outputs to left and right speakers as a two-channel amplifier. No fader feature to for rear left and right speaker connection. An external fader that mounts to the row of center console press in controls where you have the hazard flasher switch, rear demist (back glass defrost). (I have this fader someplace, I guess. Unsure.)

There exists some useful information here. You will see what is missing from the wire harness sold with the radio accessory installation kit.

I found images on an ended eBay auction:

Click the SOLD atop the radio image in the blue box at the page top to open the ended auction. Sold in Medford, OR for 160$ US.

I found two diagrams for a radio circuit in 1997 imprint Haynes 240:
- 1997 Haynes 240 p12-22, 1976-1979 Radio (No wire colors)
- 1997 Haynes 240 p12-27, 1980-1983 Radio (Shows Wire colors, with wires out of the radio, a connector, intermediate wires of a different color, a connector, and different wires at the left and front speaker. No rear speaker wires.

Colors don't match. Yet the harness that should be connected to the wires terminating in the connectors on your radio are not there.



You can see the connectors and on either side the conductor color changes. Yet is a two speaker radio. No rear speakers. Some detail may be missing.

The image is 900 pixels wide here to fit into the main text flow column on page display. The actual image is 1576 pixels wide.

Here is a link on the same radio model of your posted by muskox37 this past June 2020.

Did not read through it all, the found the above image for Mr. Muskox37.

I'm unsure about the wires coming out. The black and black yellow wire are left and right speakers. The other single conductors in red, blue, black (ground) and light blue (power aerial?). You may need to figure the ground, power, and other single wires to connect to a fused 12 VDC power, turn on the radio, attach a small speaker to each of the black paired wires, to figure out what is left and right. Don't short any of the wires. Only the black single wire connects to the metal frame under the plastic kickpanels and section surrounding the center console.

I'll guess you have some testing to do. Nice winter project! Yet watch the interior plastic section as they get brittle in cold weather!

Questions?
