VHS radio hookup question

[lakeeriebum]

Hello,
Trying to hookup my marine radio. No manual. There is a black/red wire coming from the radio itself and blue/white coming from the aux. (I think). The wires are right there by the radio, just don't know which wire is hot from the aux side. This boat is new to me.
Anyone know off hand? Sorry for the newbie question.
Thank you!

It would be nice to know what radio you're messin' with.

Agree, need to know what radio.
Guessing
Red +12, Black Ground, Blue/White back lighting

Blue with white is a common gps input wire colors p

The wires on the radio are black and red, this is a no brainer. There are 2 wires (blue and white) that appears to be what it was hooked up to, most likely from the auxiliary. My question is: does anyone know how these hookup? red to blue? red to white?

 

[alldodge]

red to blue? red to white?

No, :nono:

Instead of one wire being blue/white, there is 2 wires and white and a blue. These wires would go to a GPS as dingbat mentioned. Connect them to power and you burn something up. Your radio probably has positioning for DCS
