I'm a bit out of my element now on this 1978 280z s30.
I believe both of the fuel pump relays are bad. Unfortunately when I ordered the new ones, they don't have the same pin structure so I have to rewire them. I'm simply not sure which wire goes where though I ventured some guesses.
Could someone take a look at what I've posted in this PDF can correct anything and tell me which wire goes to which? There is a 4 pin and a 5 pin.
