I have a 94 vert I just swapped an s13 blacktop into. The harness and everything was already done by the previous owner. I swapped everything in and it runs great. But when shutting the key off I got the buzzing egi relay?? Well I searched this as much as I could and found if you pull the meter fuse I get no buzzing. Well most of the things on the meter circuit come from the ecu right? So I pulled the ecu fuse, and figured it wouldn't start...I was wrong it starts runs great, and my wiring gremlins are gone. Anyone ever ran into this before?

Thanks and happy Easter!
