Grid heater relay swap

[CdnHO]

Has anyone tried installing a 2019 mechanical intake grid heater relay in place of the solid state model on a 2020 or newer Cummins powered truck?

I was wondering the same thing? provided the cable lugs are the same size which is probably the biggest issue , seems like a $80 relay is quicker and safer investment than waiting around for parts and your truck possibly burning up?

So I found some pics of it and the plug that looks different along with the mounting. You would likely have to rig up some kind of jumper along with changing the lugs out as they look way different ? also the solid state relay must be to allow the grid heater to ramp up slowly rather than full instant on like a mechanical relay? Maybe it's a way to save the grid lugs from burning up?
