ASTRA DIGI DASH SET, HELP!!! WHAT BITS ARE NEEDED FOR SPEEDO

[az_e11]

when i bought my digi dash set, the extra bits that i was only given, was the black top transducer bit with 3 wires on it, in the picture, link below

Do i also need the white bit in the pic , which is cnnected to the black transducer thing


or can i use the 1 already on my Nova gearbox, which i was using for my standard dash

you dont need the white bit its already in your gear box.
just unscrew the black bit from the white and then screw it back into your gearbox
