This is just a quick update to say I’ve been working on this steadily for the last few weeks. The PCB finally arrived earlier this week and I’ve got a board assembled and working.
This project is proving somewhat of a challenge. I’ve now bought two Universal LCD instrument clusters to test with and this is where things got interesting.
The second one I bought came without any instructions, I contacted the seller and they said sorry, we don’t have instructions for it. Now you might ask why did I need instructions for this one if I’d already got one? The answer is that while they look identical, the second unit is different, you enter setup mode in a different way, it configures differently although it has the same options and the 20 pin connector on the back of the unit is wired completely differently. The four connectors on the other end are wired the same but I’d bought some 20 pin connectors so I could make my own connector cable up. This second unit also seems to be more consistent at converting speed to minutes compared to the other one.
Anyway, I’m just working through what I hope are the last few little issues and a more detailed write up is coming…
