ive worked out what is what on both now....

and its time to actually wire this puppy in.
i have two wire looms for the sti dash so i should be ok.
(my car it cant be removed)
i hope all the signals are the same. (speed tach heat fuel etc)
i will post some pictures and a diy if it fires up ok to help anyone else who wants to do this.

then just for the cutting fitting in the dash itself......
will post pictures and give pinouts to anyone else who is interested.

i have never been able to find a diy to put it in an older beast like mine.
