Salam. I've been facing some issues with wiring a speedometer so I thought I'd ask here for help. I've got the speedometer of an MK3 VW Golf and me and my electrician are trying to install it in a Chevy Joy as it fits pretty nicely in it and is a good looking cluster. Now we've got the speedo and the rpm portions working but we cant figure out the connections for the fuel and the temp guauges as all the wires are white and not colour coded. So, I need the wiring diagram for the MK3 cluster. If somebody has it, I would be very grateful if they post it here. The diagram should show the pins where the wiring grip sits at the back of the meter and the connections related to them so that I can follow it to connect the gauges. Or in anyway helps me figure out the connections. Thanks in advance.
P.s. This is what the cluster looks like,
