Connecting two Wideband gauges

[jeanno]

I would like to connect two wideband gauges in order to log two lambda values in the same time.
I guess the only way to do this is using analog input and output (unless a gauge can be configured as an AIM
transmitter ?).
I would like to verify how to wire this connection :
On the wideband gauge that will send the lambda measurement I would connect pin 9 of SubD15 to ground.
Then I would connect pin 1 of this gauge to pin 8 of the "receiving" gauge (to which I would connect with Vemstune) trhough a resistor.
Is this correct ?
Would a 10k resistor be OK ?
Thank you for your answer.
