Best way would be to measure the resistance of the solenoid directly. Probably easiest on a V6 or for somebody using a pigtail to plug the connector, just because it would be difficult getting probes on the pins from what I remember from disconnecting mine.
Regarding resistors, some of those "anti hyper flash" ones for upgrading to LED turn signals may be an option. Low resistance, but could be wired in series. Use the other side of one of the pigtails and it should be a plug and play solution once we know a target resistance.

SOL POPPED A CEL....
For me any resistor bigger than 1W calls for a more practical solution. I am not into roasting plastics...
If you don't like to use a bulb, then wire up the coil of a spare relay.
The lower limit may be 150mA, it's a pulsed digital voltage from 10 to 90% duty.
This dummy load only useful if a specific range of ECU pop CEL... perhaps these ECU use reverse logic we don't know about. "Power needed to shut solenoid" ???
Don't make the wrong assumption to disregard what you don't know (I don't know that for sure either).
If i were you... I'd keep that all factory plugged until you can confirm how your engine controls interacts with your oil pressure.
And while at it perhaps we can all understand why your engine has CEL this mod....

Or can you buy another solenoid and plug the engine harness into this ... and leave it dangling or zip tied ... the OEM solenoid will remain unplugged

There is a harness inside the timing cover/oil pan... I am not sure the connector of solenoid and the external connector style will match without internal harness... 50/50, right?

I'm away from my desk with WIS. Wondering if anyone can help find the part number

I think a good way to get through this is to look for a P06DA00 via OBD-2 generic. It should NOT appear there, but if it does, you have a "lucky" ECU....

278-180-04-15 appears to be the solenoid. Actual picture of the part here: https://www.autohausaz.com/pn/MB-2781800415
It appears the solenoid should plug directly into the external harness without the need for the internal intermediate connector.
The internal connector is listed as individual pieces with a housing part number of 029 545 10 26. Scrolled back through this thread and found that matches the housing that plugs into the outside of the timing cover.
References: EPC section 18-015 (engine lubrication->oil pump), post 484 in this thread.

Getting to the Root....
My brother in law just bought a 2017 GLS550 with 131k. M278. Thing runs flawlessly. I helped him unplug but he has a P0496 evap code (which he probably caused by not tightening the gas cap). Chasing that will make it tough to immediately notice if unplugging is causing a CEL.
I think a good way to get through this is to look for a P06DA00 via OBD-2 generic. It should NOT appear there, but if it does, you have a "lucky" ECU....

"Unplugging oil pump control solenoid triggers CEL in M157
-- Perhaps the crankcase or intake pressure upsets some of ECU expectations. Perhaps the engine came equipped with an optional oil sensor. Something's different!!
-- Based on all known reports thus far, ECU does not CEL open solenoid circuit.
-- Let use a reputable scanner (Xentry, Launch, ...) with a solid scan of at least the ECU.

Let's try to get to the bottom of this issue for our collective interest:

I could be totally wrong with the conclusion from the inferior scanner.
Also, it's m157 not m278

In the OBD2 generic menu, there are 3 components, engine, AT and FPCM-FuelPumpCtrl.
There is only one code found in the engine category which is P06DA. The rest of two categories passed with no problem.

Forking self-help path....
Thank you for pointing that out Peter
We can say that some ppl with M178 and 4Cyl have reported an active CEL from faulty pump solenoid circuit.
That's interesting!
Again I would recommend not to disconnect factory systems hopping nothing's changed. Bosch excels at managing zillions of different options. Who knows what combination they wanted to test ?
I'd recommended to open a thread under affected chassis forum or in Tech Talk... then we can try to help with specifics.
Here is a course of actions:
-- check live oil pressure activity
-- check solenoid linked to DTC
-- Test dummy load (bulb or solenoid)
Outcome CEL is reworked to be bypassed.

If this is the case, then simply plugging in a dummy solenoid will not remove the CEL.

Go ahead and create a new thread under your own chassis forum.
We'll try to help you remove all the bad to enjoy nothing but the good.

So His take is a healthy engine could have accelerated wear due to cold weather start-up stress in a cold climate when unplugged.
