I added 2 spst relays, one was for the injector live feed, but I can't remember off the top of my head what the second was, it was simply done due to the differences in the looms as not every sr engine loom wire has a matching wire on the n16 interior loom and a coupel of them were switched live feeds, so instead of piggybacking them off of another switched live I fitted relays, I put them behind the passenger side kick panel using the same bracket that's used at the drivers side kick panel for the fuel pump relay.
