Default Replace DERM 90'

I'm finally getting around to replacing the DERM in my 90'. I've read through the FSM and am just wondering if anyone has an easier way then the FSM says. Easier and faster is always nice. Thanks!

Not that I have found. I took mine out and sent it off for repair this last winter. I still have an issue, checking the grounding next, as the frame rail sensors ohmed out correctly.

How hard was it to remove the derm? How long did it take about?

The right tools at hand it took me 1.5 hrs to remove the "stuff" required to get to it and get it out. Fourth one I have done. Going back together is another thing ...entirely.
