The same way you install it into a magna.

yeh same way as any other car

sorry guys i should have been more specific i ment wat wires are wat

red = positive
black = negative
yellow = accessories

then just look at the back of the speakers for the wire colors.

its not hard man.

...On the head unit they are the right colours....in the car is another story (car manufacturers in 89 didnt tend to colour code them the same as aftermarket HU's).

you want to find the wires:

ignition +ve
constant +ve
ground
antenna
speaker

antenna is the easiest, different looking wire with diff plug,
ground might not be a wire, it might just be a connection to the chassis,

***For the rest it is a lot easier if you have a multimeter (you can get a cheap one from dicksmith or something)(Pretty much any cheap one will work)***

pm me about how to do the rest once you have one and i'll be more than happy to help, I'd come around and help but I'm in SA.

call a decent car stereo place, ask them for the install guide, see if they'll print it out for u if u really cant be stuffed with a multimeter :P

installing headunits is easy done in any car, aslong as you know what you're doing. To wire up a headunit loom should take no more than 5 minutes, grab a testlight and find power, acc and earth then grab a battery (9v or whatever you have lying around) and tap wires untill a speaker pops, so when you hit the two wires for just say the front left the front left speaker will pop. Then to find electric antenna attatch the testlight to 12v and start touching wires, when you hit the electric antenna wire the antenna will go up. Thats how we do it at work lol
