crossposting to 700 board, since some of this is relevant to your cars as well. (2-stage foglight switch may not have been applicable to 700's, as some had two separate switches, with much larger electrical connections than on the later style)

finally did the e-code install to my 945 yesterday. Went pretty smoothly, and am quite pleased with the results. RepairmanJackal's thread
Convert US-Spec w/o Fogs to E-Code? has tons of good info on the process and the parts needed, I'm sharing my photos in the hope that they will supplement the existing info and encourage others to perform this upgrade.

only snag I had was with the corner lamp bulb holders. Neither the US market 940 ones nor some later ones (from a 960? and 850? who knows) would fit the european housings. I ended up wrapping electrical tape around the sockets to buld them up enough so the ears would do their job and hold the socket to the housing when rotated.
