430 wiring help

[rwarre]

I purchased a Garmin 430 from an avionics shop that has been tested. It came with a wiring harness that was just cut from the components. Now I am trying to decipher the installation manual to decide how to connect this unit. Are there any books, or materials that would be helpful in finding out what all the terms means and how to apply them. Example 10 altitude out pins,com mic audio lo, com mic audio hi. I have thought about having an avionics shop wire this for me if the group thinks it's too complex. I did do a electronics correspondence course many years ago and do understand basic electronics. Thanks Randy

There used to be a link somewhere that may have had the pin-out info for the 430. I will try to find it but don't get your hopes up. No doubt if it exists someone else will provide the info.

This may be it. I could not get the link to work so I have no idea was the problem is.

Randy,

Do you have the install manual or the operation manual? You will need the install manual.

These are hard but not impossible to find and download on the web.

I downloaded the installation manual. Rev B, I understand there are later Revs. I am sure I can figure out most of the connections, but like I stated, when the manual talks about hi and low audio I don't understand if that means frequency or something elso. Randy

In Garmin install nomenclature, hi means signal, lo means ground.
