    How does the cluster lighting get power?

    Full disclosure: I’m terrible at anything electrical/wiring. I’ve done engine swaps, cam installs and diff rebuilds but I struggle with basic wiring. Please break it down as simple as possible, I’m an idiot!

    my cluster no longer lights up when the lights are on. The bulbs are good, the SI batteries were just replaced, and the other systems respond normally to the dimmer switch. What connectors on the back of the cluster provide power? What specific wires should I check?

    for wiring reference: 1987 325is.

    thanks!

    Power appears to be the Gray/Red wire coming in on Pin 23.
    Ground for the same circuit is Brown/White on Pin 24.
