i just swaped a b20 into my 92 hatch and i hooked up the battery and had no interior lights. i put a diff main relay in and still no lights. then i moved the batter up to the front from the trunk n hooked it all up and then i had lights. but shortly after they cut off. i know the pos/neg are right in the fues box because my friend had the pos n neg switched in the fues box when he had a b16 in the car before me and he blew like 3 main relays. im not sure what is making the car get no elec at all. there arre like 4 wires off the ecu that arent connected. idk the wiring is kinda sketchy for that. but would that mean it wouldnt get ne elec at all? any fuses i could check? i dont think the main relays keep blowing, or what could cause them to blow? idk at all. when i pulled my b18b out of it it was fine.
