Hello chaps I might get told off for being in the wrong place but here goes , I have recently bought a tuning box from a vectra owner off ebay his car was a 1.9 cdti and i am trying to fit the unit on my 1.7 cdti astravan . Now i have been told that the unit/box will fit but I have not got any instructions and am guessing the 1.7 and 1.9 arent that different .

Any help , diagrams , pictures , instructions etc........ Would be greatly appreciated , thanks in advance Scott
