run it like this:

black brown -ground
red - power
green - rpm
grey -tps
yellow - pressure in
white - pressure out

orange, pink, blue not used. i heard some peeps run blue to o2 sensor, that correct?

 

 

That's about right. The Blue wire is optional to the o2. Sometimes it works, sometimes it doesn't. It didn't on my car

 

ok manual says that the afl is the pecentage of the air flap being used. since the blue wire is going to the o2 sensor this should read a/f ratios correct? also its in percentage. this percentage translates to the a/f ratio then? ie 12.3% = 12.3:1
