Freedom 458 installation on 1985 pt-40 ?

[John Mann]

I Have a 1985 pt-40 with the PAC 2000 inverter and the old battery
cookers! Just aquired a 458 2000w inverter charger. The old PAC
inverter quit working some time ago. I want to replace the two old
chargers with the new 458 and remove the old PAC inverter. I am
wondering if anyone has directions for the replacement of the old
chargers or schematic pictures etc of what needs to be added or
removed on the coach. Thanks for any help I have searched the site for
previous posts files etc but have not found what I wanted which is how
to install? Appreciate any help Thanks
