Does anyone know the location of the booster pump #R66 on the vehicle?

It is listed under two part numbers in the Porsche catalog for what looks like the same application for 1995 on up:
A993 615 135 00 and 999 657 008 90
Are they really the same form/fit/function?
Both seem to be superseded to a 999 657 017 90 aftermarket on-line.

Any feedback would be greatly appreciated.

on my 95 there are three relays on a small block inside the front boot. passenger side fender wall under the carpet. you will probably need to remove the spare tire for decent access. I have a couple extra of these relays if you need one....

Thanks for the offer Stace, but I already ordered replacements. In my USA 96' there are only two relays located there under a plastic cover. I wonder why my 993 only has two when the catalog lists all three?

possibly used with ABD?

I do have three in mine. two are the identical relay. the third one is a different part number. mine is a C4 and the braking system is different than a C2.
