1 is the code check connector.



I couldnt find 2 or 3 in the wiring diagram. They must not be important.

#2 is the "initial set coupler" same thing as the "ten" terminal on the fd



the other green one is for the diagnostic code reader.

for diagnostic presumably..

if not.. need to find the offending wire to connect this to then...

looks like the trailing coil has this as well..

Yes, its for diagnostic. Nothing needs to be connected normally. Same goes for the green connectors.
