Anyone know the speaker / power wiring for a 93 Magna Exec Wagon

Have you got the H/U removed? If it's anything like the 95ts wires i'll be able to help.

im about to work on my magna so ill have a look at the wiring on mine but from memory the red green one is the main power, ill get back to you on this soon!

get a testing tool there $2 solves all your problems.

Ok here goes...

Red with green = constant 12v

Blue with red = Ignition

Green with white = Headlight dimming ( H/U dims when headlights are on so it's not so bright ) My new H/U had an orange with white wire to connect to this 1 was labeled " Lumination "

The ground wire for the stock H/U is conneted from the units harness to the chassis ans is Black with yellow. Remove the screw holding this in place at the chassis and replace with new H/U ground.

Car ariel is standar issue so no dramas there.

Also remember to re-connect the in car lighter back light and plugs.( Black plug left, grey plug middle and the light has it's little hole to go in ) And remember to re-connect the ash tray/coin holders light plug ( do this before fitting the console, otherwise, like me you'll have to remove it again to do it.

Make sure you seperate the power mirror " loom "(is that right? ) from the stereos one. You don't wanna cut the wrong wires.( no I didn't cut the wrong ones, but almost lol ).

Hope this helps ya dood.

This was all on a 95 TS so they might differ a little but with a $15 multimeter from silly sollys you'll get it right easy.
