Default YGE rpm lead brown cable?

I am using a YGE 90LV V2 and want to use the Spirit gov.

On this ESC the rpm signal is on a split lead with one connector being only the rpm signal and the other connector being the 'slave' BEC power.

The rpm signal goes to the middle pin (pit). But... then it seems like some info is missing. or I am just being daft.

It says "It is important to connect the brown lead as well, to prevent extraneous radiation"

Sooooo, does that mean the brown (ground) wire from the BEC should be moved to the rpm connector which would put it into the Elev port ? Surely, if the slave BEC lead is being used (Y-connected into a servo port) the brown wire will already be connected.

It seems like what is left out of the info would be a line that says something like "if the slave BEC power lead is not in use... at least connect the brown wire...." but then, that seems kinda strange to me :-o

I'm just super cautious before putting anything in the elev/pit/ail ports so I want to make sure it is totally correct.

if i remember correctly the older YGEs (i had i.e. a 90+120LVK, but on vbar then) it is just BEC master & slave plus the orange separated pin for rpm signal. so it's master=>THR, slave=> AUX (or any other power-connector) and the single orange one to the middle pin (PIT). that's too what is written on the old (paper) German language manual i have here... the English translation of those German manuals seems to be a bit unclear/odd/strange

Ciao
Michael

Thanks. I guess I was not clear that I am talking about the Spirit instructions about the brown wire: YGE ESC RPM output - Spirit System Manual

aah i guess they only wan to say: do connect ground of the slave cable to to avoid signal problems (noise)... but of course to ground on the Spirit. i agree this is not really clear!
