I got this cluster off ebay, thinking that it would work on my 98 rs. But all the harness's don't match my car. here is the link for the pictures. Can someone tell me what version cluster this is? THanks

Is it possible to wire it to work in my car?

That wont work unless you drive a GC8 bodystyle Impreza. Not the current GDA (bugeye & '04 bodystyle)

I drive a 98 rs, which is a GC8 style, GM6 actually. But the guage i got is actually a version 5/6 which only works with 99-01 models. The one i need is a version 4 sti cluster. I already ordered one and i'm giving my version 5/6 to my girl friend. She drives an 01 rs. Thanks though
