You can use terminal blocks like this: Component terminal block - PTTB 2,5-R499/O-U - 3210925 or Double-level terminal block - PTTB 2,5-LA 24 RD - 3211456 or Disconnect terminal block - PTC 2,5-TWIN-TG - 3270091 with Component connector - P-CO - 3036796 Then you have your pull-up resistors in a terminal block with easy wiring. regards CaOd
