Thats what my cars doin now! Might be my problem. But your relay might have a part number on the side. Or just bring it in and they can match the plug for the stock pictures. I used to work there lol

get one from Honda. Tell them the year make and model. They should be able to find one for you. They're about 70 bucks.

The guy at autozone wasnt so helpful-_-
Well the showed me a picture of the relay off a 90 civic which is what i drive
and it was much smaller
so now im guessing since i have a b16a swap the guy before me must have switched it or something
Does anybody know a honda car model with the same looking relay?..

Any main relay from an EF should work. Or just get one from Honda as stated above.
Also, that relay is not changed when a swap is performed.

I think I pay about $5 for a main relay at the local wreckers when I'm yanking EF parts.. If you have a local yard, try there first.
