Hey thanks for the reply!
I ended up paying a few $ for the connectors on ebay, really absurd pricing. They're some sort of JST connectors (PR or something?)
I did not know the bitmain boards used the 4.7 / 4.9 k resistors at the time, I ended up buying those and everything is working great!

Are these the correct connectors?
Pretty hard to tell, all I know is that they are 9*2 (18-pin) connectors, zeusbtc sells them for 50 cents, how much did you get them for on Ebay?
can someone confirm the resistor values or provide insight on what they're doing? does that resistance value matter that much or would, say, a 10k work fine?
Why not get the 4k7 / 4700-ohm resistors as they suggested since those are the once used by Bitmain anyway? is it hard to find? they seem pretty cheap on Amazon. I am not sure why are you trying to risk trying something different, would love to know why.
I also think NotFuzzyWarm or HagssFIN will assist you best on whether or not you can other resistors and on what they actually do.
bought the connector from ebay, caved in
Looking for the resistor.
Other videos suggest its 0201 package or smaller
On mouser/digikey they have 4k87 at this package size

Hi All,
I looked through the following threads:
https://bitcointalksearch.org/topic/more-that-3-hashboard-on-s9-5190613
https://bitcointalksearch.org/topic/m.12529952
https://bitcointalksearch.org/topic/connecting-three-antminer-s7s-to-one-controller-1234807
Trying to do the added connectors mod as well.

From that photo looks like 4k7 resistors, either 0402 or 0201, looks like 0201 to me
I can't find the part number for the connector though. Thread above narrows it down to this one:
