Hi people just doing some work on a new to me truck - in replacing the stereo I'm not getting into any power at all the stereo and lighter are not working fuses are ok - I'm not to well versed in electronics - where should my next focus be beyond the fuses?

 

Just how are you checking for voltage??

Is this radio just going to plug into the plug on the harness??

 

Replaced the fuse in the stereo and it fired up. Old fuse didn't look bad but that solved that. Looks like the previous owner monkeyd with the lighters wiring so I'll just have to go to town on that.
