Narrative:
Scheduled part change for part number-99-2427-9-9001 serial number xyz, relay bus/generator power. Position left APU. Beginning the shift, lead told me you have schedule part change it is relay left APU bus/generator. Lead asked me do you know where is that relay. I told him no I have to look in maintenance manual or ipc. He told me it is located behind flight attendant seat. I took off flight attendant seat. Removed panels. Behind that panel's left position just only 1 relay. I did not checked serial number because the only 1 relay was there. Removed and replaced. Before close panel and put seat back, I called lead to come and run engines. He came, ran engines, he did not say anything. Just operations check good. Close panel and put seat back. It is good I close panel and put seat back. Later, 1 week, they told me, you took off wrong serial number.
