How to build EIS/ELV NEC adapter for VVDI MB Tool

HaveEIS/ELVcable tester for your vvdi mb tool? Think it expensive? You can make EIS/ELV NEC adapter by yourself and save a lot.

For Mercedes W204 W212 W221 W164 W166, its necessary to have this adapter to use with the EIS ELV maintenance, Mercedes key programming and key detection.

Here are somediagrams for reference.
W164 / R251 / W221 / W216 with NEC inside
w203 / vito w639 with mcu HC908 inside
w203 with mcu hc912 inside

W204 / W207 / W212 with NEC inside

W210 / W208 / W202 with HC705 iside

W211 / W219 / W209 with HC912 inside

W220 / W215 / R230 with HC705 inside
But if you are not interested in building one on your own and want to spend a little bit more money to get a working EIS/ELV Tester, then this is a site that has been confirmed working by some of our mb friends:https://www.eobdtool.co.uk/wholesale/xhorse-elv-emulator.html (xhorse elv adapter); https://www.eobdtool.co.uk/wholesale/vvdi-mb-nec-elv-adaptor.html (elv adapter); https://www.eobdtool.co.uk/wholesale/mb-eis-elv-test-line.html  (eis/elv test cable)
... I wouldn't recommend other sites, although they may work, problem is that they have not been confirmed working yet.Functions of EIS/ELV adapter at eobdtool has been tested for years (many discussion in forums).
