woodymi16 24 2 Cars Posted March 9, 2019 Bought a replacement tacho but noticed there is an additional wire on the new one, is it going to work ok. Share this post Link to post Share on other sites
SRDT 177 Posted March 10, 2019 This could be a late unit or a spare part, on the loom the 4th pin is only used by the XU5M ecu and the diesel crank sensor. I wonder if that means this tacho can be driven by a modern ecu just by using that pin. Share this post Link to post Share on other sites
SRDT 177 Posted March 11, 2019 Do you have a part number with the new tacho? It could be 6113 93 the regular one since 87 or 6113 K0 fot the XU5M or 6113 K3 VEGLIA 0981 029 9962 with catalyst. Share this post Link to post Share on other sites
