1997 Southwind Storm 34LS - NEED WIRING DIAGRAMS

I wouldn't get too concerned. I asked Fleetwood for the location of water pump relay and discovered that it could have been in one of 5 location's. Given the age of your rig you may discover your rig didn't come with an inverter but just a converter and any inverter was put in by another owner. As someone else indicated - the mfg of the particular device is better source for wiring on any specific product.
