aeroforce interceptor for speed and tach

[tony2tall]

I am researching and about to tear into my wiring harness following the instructions on lt1swap.
I plan on temporarily using an Aeroforce Interceptor scan gauge I already have for the speed and tach.
So I think I would not remove the VSS and Tach signals from the PCM connector as instructed? And leave them alone since I will be reading these through the OBII port?
Also, I hope to someday get a Dakota Digital gauge cluster, so would this same answer apply there?

Thanks!!
