swaping perc card in DELL PE 2900

I had this question after viewing Upgrade RAID Controller card on Dell PowerEdge 2900.

I got a 2900 from a school I work at. I'm still a student myself. I heard the h700 would work and I blindly bought one so I could use my 3TB drives in the 2900. but there are two connectors that connect to original raid card that seem to come from the HDD bay, but the new raid card doesn't have those connectors, I'm lost as to how this is gonna work. any hints?

You need to get new cables with the SFF-8087 connectors for the controller.

SFF-8484 on the backplane of 2900 I believe same as in photo 1 but the other end.

https://www.amazon.co.uk/Cablematic-Mini-SAS-Cable-SFF-8087-SFF-8484/dp/B007G5U69M looks to be what you need, you will have to throw away the cables in both your photos. (or sell them on eBay).
