1973 Chevy Blazer Ok I don't have a 12V test light handy so I figured someone one here would know for sure. I'm wiring in my new mp3 player and need to provide it with an "always hot" wire in order to run the clock, save presets, etc. Since my Blazer has never had any stereo except the stock AM pushbutton radio with no clock, there is no wire readily available for this purpose. The white arrow represents what I think would be an "always hot" connection (BAT.). It even has an extra unused wire coming off the plug (it's the wire that the white arrow actually points on). This is what I think I'm looking for. The red arrow is what appears to be the accessory wire (power only when key is in "run" or turned backwards). Am I right? School me or make fun of me if I'm not.
