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.

Superhawk,
Many thanks for the relay board diagram.
Any idea on where the fuel pump is grounded to?

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.

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

Now I know who to give credit to - that is an awesome color overlay and labeling job

Thanks for producing that ! @http://www.914world.com/bbs2/index.php?showuser=1143

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

Yes, thats correct. Check the circuit with an ohmmeter if you need to confirm it.
