Hi all,

I have an older Clifford matrix 50.5x that I had installed in 2008-2009 (for a lot of cash back then!) and recently the antenna wire has dry rotted and I think the wires touched, which fried the ANT input on the brain (Clifford actually said this could happen). I ordered a new antenna wire and base with no luck even after I reprogrammed 2 remotes. Works prob 10% of the time and lcd doesn’t update.

No luck finding a 50.5x brains online but I see eBay has viper 5900s. Does anyone happen to know interchangeable models that will plug in?

Greatly appreciated and happy holidays!

I think you want the Viper 5900. If you search eBay, you'll see a listing for a brain only for cheap.

Thank you! That’s what I saw in a post online too, I saw that brain for $22.xx and I assume it would be plug and play. Def worth the gamble vs $700+ on a new one!

This the one you’re referring to?

Thanks! eBay link

eBay listings don't work on this site, but that's the item number. Also, it might plug right in but doesn't mean it'll just be plug and play. You may need to adjust some settings in programming. Here's a link to the installation manual: https://www.the12volt.com/installbay/file.asp?ID=618
