Looks kinda stock to me. The only symptom is the tach stopped working?

Whole cluster stopped working , other than the fuel gauge . All the lights work tho. Wasn't sure it looked kinda hacked to me that's why I said something

Sounds like a 99 Civic EX. Coupe or sedan?

Speedo -- Is CEL code 17 thrown?

The 99 Civic EX has OBD2b wiring, which gets the tach signal from the ECU rather than the distributor. That's likely why your tach doesn't work.

The ECU has a white label on it. Post a pic.

You have a stock P2P ECU for the D16Y8 engine. It's not chipped.

You don't need a code reader to check the codes. Just jump the service connector.

Check whether the cluster receives rpm and speed signals. If so, the cluster or gauges are bad.

Nothing but I just tested the test signal and it works but I realized something..... not a 99-00 ecu which means that's why there is no tach it gets it from the distributor

Only the tach is wired differently. The other gauges are wired the same.

The speedo is a separate issue.

Are you saying that the cluster is receiving both speedo and tach signals?

I tested it and no tach , my vss isn't hooked up yet so I'm not sure plan on doing it soon so I can see if I can get anything to work. Currently nothing works other than lights no gauges at all
