rb20...Plug location

[sololock]

have some plugs on my S1 rb i dont know where they go, if someone could please help me that would be great. also where is the 02 sensor plug located?i even tried looking off a friends S2 rb and still couldn't find them.i know the brown one goes to the ACC but i couldnt find the 4 plug male

these are off the ka lower harness, not sure if these are even neededthese are on the Rb harness, i know one is the MAF that i need to extend but not sure of the othersthis is right by the MAF plug, im clueless

the big plug at the bottom is the plug you wire into the 240's harness. the red and black wire, white and black wire, and etc. cant see the rest that well

on the second pic, the small black plug is the starter signal wire, u need to replace it with the rb plug. th larger plug with the yellow wire is a temp wire i beleive. there is a plug right by the oil filter on the rb motor that has the same color wire. it needs to replace that plug. this is if you are using a modified ka lower harness.

02 sensor plug shoud be further back from the maf plug. its coser to the ecu, about 2 ft closer. and of course u know the 02 sensor is on the turbo elbow.

rbforums.org has a pretty good wire write up under r20det into s14.

sorry told u wrong, the plug with the yellow wire is oil pressure sending. the one on the rb has two wire but you only hook up the yellow one according to write ups, however mine was green with a yellow stripe. dont connect the blue one to anything.

maybe im confused b/c i never got a rb lower harness with my swap? I cant just use a KA one? also where is the big plug on the bottom of my pics exactly suppose to go? near the pasanger headlight?

edit: yea figured out the big 6 plug to the oval one..still cannot find the 02 one though.

you can use ka lower harness. the starter signal wire plug needs to be cut off and solder on the rb on, oh wait u dont have one nvm. is ther a connector by the oil filter for the oil pressure as i described a few posts up? also unsure if transmission plugs will match as mine didnt
