for those who dont know, am building an f20c ae86

almost done!

but ive come across a minor problem

two o2 sensors
now i know one goes into the headers, and one goes to the cat...

and il have to do the 02 cell fix... anyways they look identical,
one has the part number stamped 508 H1
the other is 508 h5,

ive left them plugged into the loom since the f20c came out of the s2k wreck so i know which went where wiring wise

but which goes into the headers, and which goes to the cat.. cheers guys

the only other difference between the two is

one has a green wiring sleeve and the other is white

its out of an 02 JDM s2000

 

i dont think it matters u can switch the sensors and they will read the same.

 

mmmkay will try both
