Need help with guage cluster

[pnoystyle86]

for some reason my guage cluster doesnt work. i got a new one from this guy in japan. that was the only place i could find it because its a hud guage cluster. anyway i thought if i put it in it would work. some people said it wont read out with the sr swap, but i have a friend with it and it works. i need advice of what to look for that might be causing why it not reading anything. both the mph and rpm cluster arent workin, everything else is.
