There is no need for a bunch of wiring. You have a dirty ground somewhere.

That's what I'm thinking too.

And I have a thought on what that might be.

Just say one went back to stock, it's a female bullet connector on the OEM sender correct?

If the (+) current drops below 11.5 volts which is easy say on the green circuit with multiple (+) devices, then the gauge readings will NOT be accurate.

If this is your definition of "seriously messed up" then the (+) draw has reached that threshold.

I accurately described the optimal way to wire a VDO gauge in post 12 and guarantee that if the gauge is wired as suggested and the gauge and sender are in compatible matched sync then the readings will be accurate.
It is not only possible, but probable in this case that a gauge with a perfect single ground and multiple devices wired on the same (+) circuit can and will provide inaccurate readings.
To be 100% positive of accuracy you need to wire the gauge accordingly to the manufactures recommendations described in post 12.
