I don't know how experienced Wayfarer is so I'll assume he's not used to installing aircraft. Please forgive me if this is too basic.
Using CfgEdit requires at least a basic knowledge of panel design & I think it would just complicate matters at this stage. I suspect the problem lies with not installing the gauges properly.
In the old days when all gauges were in GAU format it was easy. This is a tad more difficult to explain now. To illustrate my point the files & folder in this shot are all 3rd party gauges. Unless you recognise them as such & paste them into FS2002\Gauges they cannot display.
