OV2640 and arduino uno

Hi people.

I would be very happy if someone could help me to connect my OV2640 module to my arduino uno.

this is a 18 pin module and the pins are:

Gnd, Scl, Sdata/Si00, D0, D2, D4, D6, Dclk, Pwdn
Vcc, Vsync, Href, Reset, D1, D3, D5, D7 NC

I have googled and googled and googled and googled and I’m going crazy because I have no idea about where these pins connect to the uno. the only instructions I’ve found are about the 8 pin module but a lot of comments about links to go somewhere to read about how to connect the 18 pin module (which is often not the 18 pin). I’ve read that but I’m not anything closer to knowing which pins on the uno they connect to.

I think I’ve got the Scl, Sdata/si00, gnd and vcc right (A5, A4, gnd and 3,3V) but I just can’t find out the others. I also tried to find it out in my libraries but with no effect.

the sketch I have does include Wire.h, ArduCAM.h, SPI.h and memorysaver.h
it does upload but I don’t know if it’s working because I can’t connect it
