backfire megasquirt turbo

After searching around, it looks like I did not wire my wasted spark correctly according to DIYautontune. I need to make sure I have coil power going through a relay that is switched with the fuel pump relay output. Where would I found the fuel pump relay output in the engine bay? thanks

Both the main and fuel pump relays were originally installed on the engine side of the fuse box. You will want to locate the 4 pin/connection relay with a 1.5mm GN/VI wire coming off pin 87. Or you could tap the fuel pump circuit inside the fuse box at F1 again at a 1.5mm GN/VI wire.
