Wire question/ speaker question

Basicly i have a few unknowns on my commando build. First, can someone tell me what wire/color goes to the temp sender. Second, where was the speaker for the radio in my jeep? Was it behind the "grill" just under the reciever? Can someone suggest a replacement. Thanks in advance.

 

Yes, the speaker was located behind that grille. Don't think I have one on the shelf to measure but they're approximately 4 inches wide by 8 or 9 inched long. Radio Shack or whatever they're called in your neck of the woods now might have a replacement that's close. If I can find an old one I'll post a picture of it.
Can't remember off hand what color that wire is but if nobody else can either I'll go out and have a look at mine in the morning.

 

Just checked my 71, blue with white stripe.

 

Thanks, i just got home but i'm gonna be able to work on it tomorrow, i'll see if i have a wire close by thats that color.
