Trying to put stereo into ke30, people who owned the car before me messed up the wiring so i have no idea what to hook the power supply on the sony stereo to? Should i just wire it to the battery or is there a better way?

Get/make yourself a test light and use that to find a wire to tap into somewhere behind the dash. If that's no good then go to the battery.

Do you need constant power or accessory power?

 

And as mentioned a test light ( http://www.ehow.com/how_7185940_make-12-volt-test-light.html gives you an idea i use 2 bits of wire and duct tape) works wonders.

I think from memory in a mates car we used the power wire to the cigarette lighter and just chucked a fuse on it

I just hooked my earth to the shell and acc pwr to ciggy lighter and then tested some old stezza wires that were sitting there and the headunit display lit up and I knew I had tapped into a power source. Didn't even blow any fuses.

^^^ As mentioned, always remember to ground (or earth) to the chassis/body of the car...

If I can recall corectly on these models, the light puprle with the red tracer wire was your accessories wire and your constant (which I also stress... FUSE it), was red. I may be wrong. But if you see these wire, splice into them and test them with a test light ($5 from Jaycar!)

thanks guys I just tapped into the battery, was the quickest thing to do.

And also the dodgiest thing to do....

Gonna be interesting when he comes out to his car on fire due to a dodgy wiring setup ;)

I hope you at least fused the wire you have running to the battery, right at the battery... otherwise yeah hope you have insurance !
