Help finding a short

Sounds like you're onto something! Try disconnecting the electric choke and see if that solves the problem. Also if the audio unit has an inline fuse, then your best bet is to connect it directly to the power feed wire for the factory radio. Just make sure the amperages match...If you can't find matching fuses, make sure the inline one is more than the one in the fusebox.

Ok doesn't matter where I disconnect from right? Choke or box
Well that wasn't it... $&@!

Edit again... I may have found the problem! Turns out the plasic case for the ac heater switchs above the radio the back broke off and the green wire under the choke wire went to this and it was touching both the temp wire and chrome plate itself. Could of caused it to ground to the dash and short?

Edit 3, the black wire on that fuse is it a ground? The diagram shows it goes to the previous fuse. Just wondering because I tapped the dash and that on the multimeter and it was connected

Sounds like your making some progress.... There never will be a "ground" attached to a fuse...It would blow instantly. The wires on top of the fuse box are supply (voltage) wires...the ones at the bottom go to their various loads. After the load (light, motor, relay, etc) THEN they go ground...Further, the switch for a given circuit can either be before the load, or after. A switch before the load is termed "load to ground circuit"...after is termed "switch to ground" circuit.... If a fuse blows, that means all of the available amperage in the circuit is going straight to ground instead of being "used up" in the load.... It's actually being "used up" in the fuse which of course, melts. Hope this does not confuse you.... you sound like you're seeing some light at the end of the tunnel!

Thanks for the help, I'm taking alittle break from it since it's nothing I really need working. Hoping a fresh start on it will help. I've decided to dig into some other things now that I have that diagram lol. Always wondered why the lights inside the heater switch panel never worked turns out it's not grounding... Should be an easy fix??
