I hope everyone is well.
I am looking for a HP THUNDERBOLT-2 F3F43AT / 753732-001 card with the HP 751364-001 Internal header cable.
The header cable is specific to the Z230 Workstation..
Here's an example of the card with a header cable for the Zx40 models from ebay.
Can anyone help me?
Ive read the following;
I'm wanting to add Thunderbolt to connect to an Audio Interface due to it's better round trip latency than USB.
I don't care about daisy chaining to a monitor.
Any help would be greatly appreciated.

FYI,.......both HP and Dell use the same Intel Reference TBolt 2 card, however i suspect each company may use a different pinout on the motherboard dell may have published the motherboard TBolt 2 pinout so check them for a cable and board pinout
the pin connections on the TBolt 2 card remains the same between Dell/HP, only the motherboard pinout may be different
as long as you get the power and ground lines correct, using a multimeter, you can then by trial and error determine the other 3 lines
dell# GGTXK is the Display port wrap thru cable
NK4P3 is the GPIO cable to the motherboard.
07HMHP is the Dell TBolt 2 card part number

The Z230 has only 2 header pins on the motherboard. The other models have more and seem, by the look of the cables to have some jumping going on.
I'm an electronics novice at best.
I wonder does anyone knows if the 2 header pins on the Z230 motherboard are power & ground?
I really appreciate you taking the time to reply DGroves.

not having this system i obviously will be making a educated guess,
looking at this document
- small form factor models – the port is near the edge of the board
- Tower models – the port is between slots 3 and 4
note the z230 illustration, it shows the 2 wires from the motherboard board connector labeled E102 go to the pins on the edge of the card this narrows down the possible connections as it will be only 2 pins so the question is which pin on the board to which pin on the card (only 2 ways to connect so you have a 50/50 chance to get it right the first time) also does the header short any pins? i would guess it does not
i suspect the 2 wires are sync signals or sync/ground if one is a ground, this can be confirmed using a multimeter simply touch one pin on the e102 to a known system ground and if it has continuity it;s a ground connection
