Trying to do some readouts. My speedometer doesnt work but the rest does. Previous owner either had an ebc and or turbo timer and spliced into wires, checking connectivity. I do have the ecu pinout diagram, but also need the cluster pinout and cant find it. Tests good from the vss to the ecu, but cant figure out the wiring from ecu to gauge cluster.

Tl;dr: what are the speedometer wires from ecu to gauge cluster? Vss to ecu is black/yellow stripe. Whats from ecu to instrument cluster?
