Hey everyone have had my 1990 TP magna for a couple years now, decided it was about time i gave her some decent sounds

Does anybody have a stereo wiring diagram or colour chart? Trying to connect the new head unit but not sure which wire connects to the acc (accessory) switch

Sorted it out. white/red is +12v and blue/white is acc

Or you could've gone to Super Cheap Auto/Repco/Autobarn and spent $14 on getting the Mitsubishi adapter and had your HU working in about 30 seconds...

one thing ill say is the constant feed and the switched are no where near big enough to handle large currents of now days head units. it would be a good idea to run a thick constant from the battrey and put an inline fuse in. dosnt take much effort and takes allot of load off the system when you crank it lol.

otherwise as long as you solder and tape connections or use decent crimp connectors there is no need for a adaptor plug lol
