I'm building Cup car and want to rip out all the wiring and just wire the necessities (fuel, power, fans, etc.) with Painless Wiring's fuse block and switch panel. Anybody ever done this or know anything about it?

Painless wiring is all GM based wiring components. Works well in the right application. The 944 is a typical German car in that the ignition switch carries a lot of load.... you can't wire up the Painless stuff that way or it will just smoke the switch all the time. You might also consider building a hybrid system by just using a Longacre or Rebco mini panel. ( Ign, fuel, momentary start button) and try to use relays to distribute the fuel pump, injector and coil loads. Greg F

Damn!

I am considering converting my 86 Turbo to an NA 944 Cup Car.

To me, the main issue in this conversion was the wiring, as I don't want to use the stock harness.

Anyone has done that before?

Yes.

Any wiring diagram and the parts used?

I just work off the factory wiring diagrams. Sometimes I have sketched out a section of something. And I have hand drawn systems wiring diagrams from the factory; pull all the parts of an operational system together from all the different pages of the factory schematics onto one page. But other than that - no, sorry.

the way i rigged up switches to control my fuel pump and ecu was just running leads from the factory dme relay position to a switch pannel i picked up it let me keep the factory fuel pump fuse and i just cut out all the unused wiring at the fuse block

replaced all factory except a few grounds with painless. npf.
