Gonna restart this thread...I have a D90 1986 exmod. there are two ports on the center dash one black, one red...would those help for intalling a radio (stereo)? All the marine radio pics ive looked at never show you the wires coming out the back!I'm guessing he is talking about a stereo. If that is the case you will need to make one yourself off of the pigtail that comes with the radio. Pretty easy stuff for even a novice.
