ovation bass repair

About a year or so ago, I bought a used Ovation Magnum. I think it's a Magnum II, the type with the slider EQ. One of the sliders broke, and a similar part is no longer available. I bought a new, undrilled pickguard from WD, but I haven't installed it yet. The question is, should I wire it as...

Restoring nice early 80's Ultra that previous owner spliced a P-bass pick guard on to for reasons unknown. Looking to replace, or find a pattern to have built. Due to the limited run of these basses, none of the pick guard replacement companies have a pattern. Thanks for your help!
