Ok I presume the two green connections are the reverse light but what about the white one my car does not have the connecting clip? Does it matter if I do not connect it?

Two red wires with the white plug is your reverse light switch,

 

cheers!

White one should be reverse if the wires are red with blue stripe. Ive never seen these plugs on a K box :/

They're 4th and 5th gear indicators. Hook up to the carb and lean off the mix a bit for highway cruising. ;)
