above my L - My Photo Gallery click, then I can at any rate see the wiring diagram. My first attempt to put images purely went wrong.

For P-Channel, the Drain would be connected to the negative terminal of the supply (through the load). The source would be grounded as would the positive terminal of the supply. The bias will need to be positive with respect to the source, so you may wish to use a positive regulator IC there. Note the polarity of the output cap as well.

something like this

edit - one of these

btw. nF sized caps , as PSU reservoir ones and output , are somewhat smallish
