Thank you, I'll let you know if end up needing it.

Wow, that would have been a great replacement. Now going for $380 on ebay for the Bosh relay! Any idea how 1 connects to the coil negative? To confirm that relay would be for plugs 2 and 3? 4 is for fuel pump stuff? ie? There is a datsun junkyard a couple of hours from me and might be able to pull them. @Zed Head which chapter or page is that diagram from? I will attempt to trace it back. Thanks for all the quick answers!

Hi there, I was referred here for answers from another forum. I purchased almost everything out of the engine bay of a 1976 280z with fuel injection. I see there are 4 plugs and 2 white wires before the firewall grommet. Research shows that 2 of them are for the Main relay and Fuel Pump Relay. Can these be replaced with an off the shelf relays? And yes I looked at the FSM, admittingly I'm pretty horrible at wiring diagrams. Any help would be appreciated.
