hey all just got a cheap headunit from cunninghams and just need a hand with just a couple of wires, I have a yellow memory 12v, a red 12v plus, and a blue power antenna wires, now which of the wires do I need to connect them to my 93 tr magna which are red, red/white, red/green, black/white, black, red/blue and green/white

Without seeing the unit or your car's wiring, I would assume yellow memory goes to the constant power wire, and the red would go to accessory (switched) power. Grab a test light and see which of your car's wires are always powered (connect to yellow) and which only has power when you turn the ignition to accessory or higher (connect to red). Unless you've installed an electric antenna you can leave that wire alone.

Although i could hazard a guess, i dont really want to because that can be dangerous. You will either need a test light or for a more advanced idea, a multimeter and check each wire individually for power, when the car is on and off.

Otherwise you might want to get someone from the 2nd Gen side of Magna's to email you a wiring diagram for the car's electrics.

Post this to the top :D

Left Speaker: Black (+) and Black/white (-)
Right Speaker: Red (+) and Red/white (-)

Ignition Switch ACC: Blue/red
Constant 12+: Red/green

Lastly the the wire that left is not needed and is not an earth :D It use to be a light for the radio it green/white wire :)

For an a earth use the big fat yellow and black cable that join to the car body shell :)

Thanks guys working good just need to put these front speaker's in now fun fun

Well the speakers I got for the front dont fit, too deep has you will know and cant be bothed to put them in front doors at the moment so gonna get some back one and a sub/amp instead

Yeah you need to make or get a verada door pod :) Then will fit nicely :)
