brown280zx Posted February 12, 2017 Share Posted February 12, 2017 So I have an rb25det neo going into a 82 280zx. I am using wiring specialties harness, with their universal fuses block. Question: For the fuel pump 12v+- wire, at which wire at the fuel pump relay does this connect to. universal fuse block.pdf It is a 79 wiring diagram but it is nearly identical just different wire colors.

Greeko Posted February 12, 2017 Share Posted February 12, 2017 Not enough resolution on the system diagram. It would go to the switch side for the relay. Thats the one that looks like a Coil. I suspect B is connected to ground or chassis and WB is signal to it. To double check, disconnect the relay and measure the Black to ground then the white/black wire to ground. You should learn to read a schematic diagram, it will really help you in the future wiring Quote Link to comment Share on other sites More sharing options...
