What does/doesn't work with the external definition?

This specific fingerprint (_TZ3002_y7wpizuw) suffered from the "master endpoint" bug where sending a command to state triggered all 4 relays at once. It also generated duplicate entities (state_1 and state_l1) when using the standard legacy Tuya converter.

The external converter provided above strictly uses modernExtend.tuyaOnOff with deviceEndpoints mapping. This successfully eliminated the duplicate entities and isolated the relays perfectly.

{"1":{"clusters":{"input":["genIdentify","genGroups","genScenes","genOnOff","57344","manuSpecificTuya3","genBasic"],"output":["genOta","genTime"]},"name":"l1"},"2":{"clusters":{"input":["genGroups","genScenes","genOnOff","manuSpecificTuya3"],"output":[]},"name":"l2"},"3":{"clusters":{"input":["genGroups","genScenes","genOnOff","manuSpecificTuya3"],"output":[]},"name":"l3"},"4":{"clusters":{"input":["genGroups","genScenes","genOnOff","manuSpecificTuya3"],"output":[]},"name":"l4"},"242":{"clusters":{"input":[],"output":["greenPower"]}}}

Start by reviewing the external-converter entry points imported from zigbee-herdsman-converters/lib/tuya and lib/modernExtend, then compare the reported TS0726 fingerprint and four endpoint mapping with existing device definitions. Done means the device is supported without duplicate entities and commands to one relay no longer trigger the other three.
