Xtrons D710G pin out required (or other xtrons)

[oookey]

hi there,

i recently brought a Xtrons D710G, possible bargain at £30 but came with no iso

i checked xtron site and they are easily obtainable but ask for the serial number, the sticker on mines gone

after searching ebay and examaning picures i found one that fits

one of the first problems is it doesnt have 8 wires

im guessing the 2 pins on the left of the connection on the back of the unit are ground and perm live

some pictures of iso leads show the other end as a possible phono input or output

also the picture on the top shows only 14 of the 16 pins in use and 4 wires other than speakers on the opposite side to the power

i dont want to spend alot on a original iso incase the unit turns out to be dud,

when i took the unit to pieces i found the following

clearly not going to work like that, the following picture shows just how bad it is

but with a little effort its now this

how ever to proceed any further i now need the pin out (what pin does what) to wire this iso correctly to fully test the unit,

someone please help
