Hi guys,

I'm in the process of doing a mechanical to electronic speedo conversion, and I have hit a wall.
The write up I have been following to successfully do this is to convert from a 91-92 model to a 93+ model gauge cluster. That is all fine and good, apart from the fact my car is a 90 model SW20 and the wiring to the back of my cluster does not match up to the wiring in the write up. The colours don't match up and it will take me a lifetime to figure it out.

My question now is, does someone have a gauge cluster diagram of a 1990 JDM SW20?

I've got the whole wiring diagram (in colour) for a 1990-1991 JDM SW20.
It would probably be easiest if I emailed it to you, so can you PM your email address to me?

Thanks Rob, but it's still not the right one. Can anyone else help out?

How did you end up going with this conversion?  I'm attempting the same conversion atm.
