Multiplex Wiring

Hi. I'm looking for a wiring diagram (schematic) for a 66 with an am/fm and multiplex. The output plug has 6 terminals and 4 speakers have to be used. I'm thankful for any info.

HERE is a thread about wiring the Multiplex units.

Chet Reed contributed the original installation instruction pages.

Just what you need!

Thanks, but I also need to know how the correct speaker wiring at the 'car half' of the speaker connector too

Study the diagrams - the info is in there.

Rear speakers are grounded to the body as shown. Only the "positive" lead is in the rear harness. Blue = Right Brown = Left

Front harness: Purple = Right Tan = Left

All speaker "negative" (black) wires are connected to chassis ground.

Thanks for the info. Mark Corbin sent me info before and I misplaced it somewhere. It would be nice to find the rear rear aux panel somewhere.
