I am in the process of upgrading my panel and would like to move the Garmin GMA 240 audio panel across the instrument panel. It would be a move of about two feet. Can I make two extension wire harnesses and just connect across? I would use shielded wires where they are already in use but I am concerned about the integrity of the extensions? Is there a feedback/noise potential doing this? Is there a better way?

Thanks 

David

SubD connectors? If it were me, I'd certainly make up a male-female 
	


extension. All the impedances in an audio panel are quite low, 

minimizing noise pickup risk. I'd consider the biggest risk the 

fabricator him/her-self. If using the quality gold plated machined pins, 

I wouldn't think twice about making up extensions.

   Agreed!  What connectors are you needing Dave?

   I may have some in the project residuals.

Thanks gentlemen. The GMA 240 has two 44-pin connectors so, I presume, I would require four connectors, two male and two female to make extension harnesses. 

Bob, if you have these connectors in your stores, I would certainly be interested in purchasing them and paying postage to Canada.

Thanks again.

Why install connectors in a location that will never need to be taken apart?

Just splice in extra wire and solder or crimp.

I think I would find it much easier to make a short extension on the bench than to crawl up into the instrument panel with my soldering iron and various other tools, but that's only me, a very old fart!

   From one ol' fart to another, agreed. MUCH reduced

   chance for errors that are EASY to make and very

   difficult to find/fix.



   44 pin devices would be the sub-miniature D-Subs.

   Sorry. No inventory on that series of devices.

Thanks for the input. I was just surfing Amazon when the email came in from Ron suggesting "Amphenol CS-DSDHD44MF0-005 44-Pin HD44 Deluxe D-Sub Cable, Shielded, Male/Female, 5', Gray". I see they also have one in 2.5' "AMPHENOL CS-DSDHD44MF0-002.5"  which I think will be perfect. 

Thanks Again.
