Main relay question
 

Corresponding to one of my previous posts I have decided to change the main relay, my understanding is that it is located under the driver side kick panel, I opened it up and there are 2 little black boxes that say Denso relay, neither says main relay, how do I know which one the main relay is?

Thanks, it’s a 97 si.

wrong location, on a 97 the main relay should be located next to the glove box behind the flat panel on the side of the dash board. at least thats where mine is and my car is a 98

Yes if it's a 97 civic si, your main relay is beside the glove box on the right side.
