Stock radio....87s4.

I can see on rear radio the following

Ground connection then 12v switched,then antenna connection, then 12v constant.

My wires from car I can see brown wire which I assume is ground, then I have 2 red wires one thicker then the other....

Am I to assume the thicker red or lower guage is constant 12 v?
And thinner or higher guage red is switched 12 v?

I assume antenna can be left unplugged

 

anyone done this??

 

Assume away. Here's a picture of the stock wiring in my 87.

 

this is a plug that goes into the back of the reno radio?
it look like ground first, then thick red, then some type of white jumper? then constant 12v thin red?

 

i wonder what white wire is, looks like a jumper then it connects upwards, maybe antenna?

 

almost there - I would think the right most red is switched power coming from the ignition switch for the radio lights. Thick red is constant.

 

does this plug directly into back of radio, or is there another plug that goes in then goes to radio?

the reason is that in back of radio, from left to right, is

[ground] [switched 12 v] [antenna] [constant 12v]

the ground and switched 12v are bigger plugs, the constant 12v is thin plug

 

direct into radio

 

thanks 86_5tiburon....that helps tremendously.....that means i can hook up

thick ground then thick red then skip skip then hookup thin red.....

the white wires i think are antenna related, or alarm? im not sure, but i dont think they are critical to radio function.

thanks ahead of time for taking photo etc, that helps a lot.....
