Post by Jasondj »

Hi all

Im fitting a aftermarket radio. I removed the factory Beta radio.

use a test light or multi meter and see which only gives power when the ignition is on,

ive even seen people use a little 12v bulb as a test light

voltage. depending on your multimeter it could just say DCV for Direct current voltage.
