Where is the fuel pump ground wire grounded? Is it in the bundle of grounds that attach near the relay board or somewhere else?
A few weeks back someone posted a photo of the 18 pin connector at the front of t he relay board. The photo identified what each of the wires in the connector plug were for. Could someone tell me where I can find that photo. I think Ive got wiring issues at that plug. Thanks for the help. EJP914 |

QUOTE(930cabman @ Oct 13 2023, 11:14 AM) How different is a /6 relay board? It is substantially different. Even the connection to the harness is different. I created the drawing above. I have a half finished one for the six relay board. Clay |

Can someone please tell me where the fuel pump is grounded?
Is it near the relay board? A stud weleded to the sheetmetal that other grounds are attched to? Thanks |

Thanks Not sure I fully understand your question Grounded to chassis ground - technically doesn’t matter where Actual ground location will likely vary depending on who touched the car last (IMG:style_emoticons/default/happy11.gif) |
