Thanks.

My radio is up and running now.

I grabbed the 12V from the glow plug relay as you suggested.

I also fished the wire from the engine compartment through the firewall to the interior of the car via the vacuum lines harness. I cut one of the ends off of
one of channels (the little tubes that the vacuum lines go through) that wasn't being used. After fishing the line through the small opening I used some black permatex to seal it off.

The radio is working fine now.

Thanks for all of the help, everyone.

If you are speaking of the black vacuum line that goes through the fire wall that is a vent line. I don't know how to word it but there is sort of a flow that goes through hat line, and it is inside of the car, so it draws in the cleanest air even though there is no filter on it.

No, there was nothing going through that particular tunnel. It was vacant.

I know there is a black line somewhere that goes to atmosphere.

This was a totally empty spot. Made it real easy.

Looks like you’ve got it under control, but there’s also a firewall opening behind the passenger-side kick panel which leads directly to the battery. I use it to power many components of my stereo (multiple amps, equalizer, and so on).
