I don't see why you need to have the contacts pulled or why you need another part (which would put the flash in a precarious position and is recommended against by Pentax). The Pentax grip does not carry any signal; you would have to use a (4P) cable to activate the hotshoe.
I use the Pentax grip with the 500FTZ with the parts Patrick describes and without any problems.

I use the the 360FGZ wired like this
MZS = Hotshoe Adaptor FG = 5P Sync Cord = Off Camera Shoe Adaptor F = 360FGZ = Grip,
The 360 dosn't have a 5P plug built into it, hence the need for the off camera adaptor. I don't know any other way to connect it. The 360 also has a little lever that pushes a pin out that fixes to a hole on the MZS hotshoe, I use this lever to apply a bit of pressure to the adaptor. Every now and then I help a buddy out by shooting new born's at local clinic. I use the flash/grip in reverse to bounce the light off the ceiling, To date I havn't dropped the flash on any babies plus the exposures are just fine.
If you know another way of doing it please let me know.
