04 top on a 97. HELP!

[Rneighbour]

Randall Neighbour here. I had to set up a new profile for some reason, but I'm an old timer here and have thousands of posts. I'm back because I have a challenge and I haven't found anything helpful with a thread search.

I have replaced my factory 1997 top with one from a 2004 boxster. Nice big factory glass window! Problem is that it's not operating right.

I need some advice from someone who has made this swap successfully. If you have taken an 03-04 top and made it work on a 97-99 MY 986, please let me know what you modified to make it work. The bolts and fit are identical... it's just the microswitches and transmissions that are not the same and it's causing operational problems.

[BTW, I found a page on Mike Focke's web site explaining it can be done, and I have emailed him asking for Maurice's three PDF files, but I have no idea how responsive he will be after all these years]

Any advice from someone who has done this upgrade would be greatly appreciated!
