Hi,

I've got a eaton bussmann fuse/relay box.

I’m wiring it up so when the main relay is switched on it will then switch on 3 relays. Fuel, ign and inj’s though pin 87.

The question I have is what’s the best way to connect the 3 switched on relays through the main relay 87 pin?

Do I cram all 3 relay wires into the 87 pin or splice in between the main relay and the 3 others.

I’ve attached a photo of the eaton bussmann I’ve got with the wire routing shown.

The main relay 87 pin is red and the yellow pins are the other relays.

Thanks in advance.
