Audio Systems: im missing the wireing harness that came with my dual raido can i hard wire it, wiring harnesses, wireing harness

Question
i bought a dual head unit from my friend but he lost the wiring harness that goes to the back of it i would hard wire it and make my own harness but i am not able to find a diagram and what probe is what and help

Answer
Dual wiring can be downloaded from their web sites.

You can find older cars wiring diagrams at www.installdr.com and you can find wiring harnesses for specific cars at www.installer.com and you can hard wire if you want to, but I don't recommend it.  A wiring harness allows you to easily remove the unit for servicing or if you want to upgrade to another unit someday.  They only cost around $10 which makes is a good investment.

You can also purchase wiring harnesses for a given automobile at www.crutchfield.com

Wishing you well,

PS: Here is a manual for a Dual model:

It may not be your model number - you did not give it in your question.  But, the wiring on page 3 is likely the same as for your model.
