Sorry, to confuse you . . .

As I posted earlier, why not just remove the bms, seal the pin hole, and let it ride?
What a topic!
but all VFCs operate the same: When I said "engage", I mean the operation where the clutch engages and it becomes a "locked" up fan. To 'engage' you must release the pressure on the pin clutch.

The hypothetical 'frame' that I presented DOESN'T exist but if it did, the bms in the vfc would bend UP and the 'frame' bms would bend DOWN; together that operation would make the clutch engage earlier. Clear????

If you remove the bms and make it a FULL time operation: it roars pretty loud and is always in operation. We want it to work ONLY when it gets to 100C as measured on the temp gauge in the IC.

And YES, my Cool Harness will work nicely on your 560SEL. .
