Need help with manual transmission engine harness mating with auto transmission dash
 
I purchased a manual transmission engine harness to convert my automatic transmission rx7 to a manual. After rebuilding the engine and connecting all the connectors to the harness under the dash(passenger side) i was left with these non compatible connectors. What's the best way to proceed from here?

I need the connector name and pin read out. This connector doesnt connect to manual transmission engine harness.

Need the names of the 2 unplugged white connectors and pin read out. Unsure what series harness this is from. These 2 connectors are none compatible with the harness that comes from the dash.

Theres a whole thread that documents what to do in this situation. It should be in the 3rd gen FAQ
