brown connector CA wiriring

[kim]

I'm doing my wiring right now I've been searching tho website and pages SR swap.com and such but I can find anything that will help.

My problem is that on my Grey and brown connector that needs modifying, instead of a brown connector my CA harness has another gray connector that looks excatly like the brown. Srswap has info that a brown wire for O2 sensor needs to beconnected to a switching 12v source but on my grey connector there is NO brown wire I have a purple, grey, blue/white striped wire but thats all that is left over. any help?
