Does anyone have or know the wiring diagram for a 190E head unit? Thanks!

I am trying to install a Pioneer head unit to replace the stock one. I took it out of my old car, which was in it when I bought it. When the guy installed it, he cut the wiring harnesses off on both my old car, and the deck. So unless I bought new wiring harnesses, I would need the wiring diagram so I know what wires go to what speakers.

Ah okay.

The main power plug has most of the wires you seek:

Brown - Ground
Violet - Dimmer
Red with white tracer - Memory
Black with white tracer - Switched 12v

The memory/switched could be reverse as it's been SO long since I wired up the radio in my cars. I'd advise a voltmeter to check quickly.

Don't worry about the alarm one. Speakers are easily found. It's best to bypass that factory fader but it's more work. Up to you on that.
