blue 90 accord

Everyone tells me my car is a classic, 28 yrs old. Over 303,000miles. She might have done her time. I really like this car, But she has been out of commission for months.
Looking for ECU/ECM #37820-PT3-AO1 320-112108. I'm having trouble matching 11208. Is it necessary to exactly match the "11208" ?
Tried one with different end numbers and it didn't light up. Any ideas anyone?
