Ok so I have a 95 sc400 obd1... I tried to wire in the electric fans to efi main relay... the car fried something I replaced ecu thinking that that was it because I have no CEL in key on engine off... I can jumper the high amp side of the efi main relay and car starts and drives but still no power from ecu to EFI relay and still no CEL... any ideas?

Also no fuses are popped I have checked those about 100 times... no one has any ideas on this?

Does any one have a diagram of the efi relay wireing

So I went Through I have no power getting to the ecu but all fuses have power there.... I have to have a melted splice point or wire... I have continuity through wires off ecu to efi relay black and orange wires... I also found that there is also a grounded controller side of relay... so a short in the ecu power side of ecu wireing, I have found that my radio will no longer hold memory, as well as the clock
