this sh*t keeps on making me mad every day
JDMb18c 97 ..harness is a Y7 98

this motor should have knock sensor right ? i got most of the wiring am still missing a few
1. in my harness i don’t have the plug that goes right behind the inj. on the 2runer on the IM
2. in the harness i got a knock sensor plug but the motor doesn’t have it WTF this is suppt to be an OB2 motor didn’t they all come with the knock sensor
3. i looked at the back of the block on top of the oil filter , and there is another plug that i don’t have on the harness Is not the nipple one that’s on the side of the filter this one is right on top of the filter

help bump

which ECU do you plan on using? the stock P73? then you need a knock sensor, if you're going OBD1 with a chipped P28 then you don't need it.
post the colors of wires going to the plugs and I can tell you what they are.

Damn, Saw this and thought I would help out, but now that I see Relic is on top of it, I will back out. Free99.. Your in good hands with this guy, he helped me out with my swap... He's a good guy!

Relic1

proof you can fool some of the people some of the time...
heck man, you can help him too. you've been through this.
I have no problem stepping back and letting someone else help.

free99

well am going to need all the help i can get thanks to the both of you

ok so if the knock sensor is on top of the oil filter (round plug) then whats the plug thats on the harnes that runs to the side of the block

whats an AIT is that the one that is on the PS line ?

pics of the plugs or wire colors are going to be needed.

AIT? or IAT?

roadracer321

I agree... pics or wire colors would be awesome!

The only other round plugs like the knock is the IAB and the purge control solenoid that i can think of, and the IAB is on the side and plugs in under the intake mani on the drivers side.

1. I think you are referring to the IAT, yours was in the air box, this one is in the intake manifold and it has a different plug
2. The y7 doesn't have a knock sensor, you will have to wire this up
3. I think you are referring to the oil pressure switch, your engine should have this in the same place as the Y7

quick question does ur y7 harness have two o2 sensor plugs.
i have the same swap and i say just get a 96-98 ex harness much easyier

HondaPartsHero

also your IACV will have to be converted to 2 wire since the Y7 is 3 wire

free99

great pics but the motors is a R not a gsr i dnt have a camera so i'll have to take some with my phone the weather is not leting me do it

free99

i can do the 96-98 harness cuz the car is obd2b that 96-is a obd2a the ecu plugs are different and the plug on the the dizzy

how would i wire the 3wire IACV to 2wires ?

free99

the knock sensor on the harnes has a square plug and on the block is round is there a way to block of or by pass the sensor right ?

roadracer321

So Im wondering why you cant cut the knock plug off the harness the motor came with and solder it on the harness you are using?

As for the pics, the Type R and GSR I would think have the same plugs on the block? What looks different?

I dont know what your sayin with the "i can do the 96-98 harness cuz the car is obd2b that 96-is a obd2a the ecu plugs are different and the plug on the the dizzy ", but worst case you cut the plugs off your harness the came with the motor, and solder them on to the harness you are using as well. I got a OBD2A motor and used my non-vtec OBD1 harness. Anything is possible with a little thought and the right tool!

The 3wire IACV to 2 wire... thats a question for someone else... I would recommend studying your wiring diagrams and see if you can cheat it out or something. Kinda like what you do with the VTEC oil pressure switch when you dont have one and your ECU requires one.
