Help Wiring Stereo

[Central coast Mariner]

Hi all,

I am installing a new stereo in the boat (old one died) myslef to save a few bucks and had a question I was hoping someone could answer for me. It is a car stereo.

I have the positive and negative and speakers sorted out, but there is one wire from the stereo I am not sure what to do with.

In the install manual it says "when this unit is installed in a vehcile wihtout ACC (accessory) position on the igintion it must be wired to the terminal that can detect the operstion of the ignition key, otherwise battery drain may result"

I have just had huey install a new etec and dont want to put anything to the new iginiton (not that I would know how). But dont want to drain battery.

Do i need to worry about this wire?

Any help from someone who know would be great.

with out that wire it wont work. its yellow i presume. The thin red wire will be connected to power all the time to maintain memory and the yellow will come on power when the radio is wanted (when your on the boat not when its sitting around waiting for you to take it out)

you can always hook it up on a switch if your worried about not damaging the new wireing and connect straight to the batery. Use the fuse!!!!!

hope it makes sence.

Thanks Vince,

I think I get what your saying.

The ACC wire is the red one and the 12V power is yellow on this one.

So if I run the acc wire thru a new switch to the positive bus then it should work.? The switch would then isolate the stereo when not using. so i dont drain the batteries?

Or you could simply turn the radio "OFF" when you are not using it .

Fair call, do I then just connect both the ACC wire and the power wire to the positive bus, without a switch?

would this cause any excessive drain on the batteries when using the boat/motor, but not the stereo?

The constant power wire which goes straight to battery is to retain station presets and the clock,the accessory wire is the power wire which switches radio on. connect both to the same fuse. run it to a switch or disconnect battery when boat not in use.
