Ka Speedo wiring

[klh6686]

Hey guys, i recently got a HCR32 w/ a RB20DET from Jarco and it was in wonderful condition and has fired up perfectly for me everytime i turn the key, however i am stumped on how to get my temp gauge and speedo to work... I am using the KA's Cluster w/ the RB's tach and the tach works by tapping the yellow/red's together. Anyways i used the RB's Lower harness because i didn't know any better at the time and i wanted to get it running as it is my daily driver and so i figured all i would have to do is swap the KA's Speed sensor in the transmission which i did and wire it up.. The only problem is that i do not know how to wire it up. All of the wiring digrams i have seen show colored wires that are different colors than what i have and i can't get anytihng to add up... On the speed sensor it has a black and green wire i believe, does one accept a 12v input and the other is the sensors output or how does it work? also for the temp gauge My ka had a temp gague in the bottom radiator hose and so i put it in the rb's bottom radiator hose and i am unsure how to wire it as well... the colors don't add up on it either, it has two wires and i always hear people talk about a black/blue wire. If anyone can help me it would be appreciated as i am riding around without a dash until i get this fixed. Thanks
