What Color Wire Is What On The Wire Harness On My 89 Corolla?

[Brendan Maroney]

I have searched everywhere, but cannot find what each wire is on here. I know what the 4 front speaker wires are, I'm assuming the other four are for other Speakers not hooked up, but I'm installing a new head unit today, and really need to find out what cable is what. I need a ACC ignition line, a ground line, and a 12V from the Battery, while there are a few more than I need on the original harness. The model of my old radio is 86120-02050 with ref. no. CR LS081A if that helps. New unit is Pioneer DEH- P3000IB. Hope I can get help fast. Want to get this done tonday :) thanks!

You can run a lead for the power and earth separately then just test for the feed that is live when the ignition is switched on (Acc).

best bet is go to halford and get a harness adapter, theyre aboutr £14 but make fitting a doddle as its plug and play. plus you can always stick the original back in if you sell the car
