Top pic, middle one goes to the gearbox loom for reverse and neutral switches. Right one is the exhaust sensor in the dump pipe right behind the turbo, left one is rear 02 sensor (not used in your setup)

Bottom pic, right hand plug is the reverse and neutral switches but the wrong plug, you need to get a 4 pin one instead of the 6 pin one. (6 pin socket has two unused that are reserved for DCCD or dual range warning lamp on applicable models)

Small 2 pin on the left of the bottom pic is the speedo but you need to locate the appropriate socket in your loom (not pictured) to see if it's the right sender. There are a couple of different types.
