Hi, Saw a couple of threads on this but did not want to re-open. I have a ~2009 MD-50B and just got a 3Z5-72640-1 tach (TLDI with LEDs) just to pull the code that the engine is now reporting.
I've found the "white" bulleted wire toward the bottom of my engine (although it looks like it heads off to the tiller loom?!). This is not a permanent hookup (I have a Zapcat/Thunderduck inflatable with no place to mount anything!) so I am not hooking up the 3 LEDs nor did I get the extension/remote mounting 2-wire loom. Now I understand that I also have to provide +12VDC to the instrument and am guessing that is via the red wire that goes through the same grommet as the yellow/white is that correct? The black and blue leads are probably for illumination I am guessing. So that leaves white male bullet and yellow female bullet.
So checking here if I am correct:
white to white in engine
yellow to engine gnd
red to +12VDC (post ignition switch)
I am hoping its not something bad. The engine has 30hrs at most but has been sitting for a while. New battery (24 size) and I tried the TPS reset a few times - even with jumping my trucks battery to see if that was the issue. After clearing the code it returned after a second or two. Engine starts and runs just fine though.
