I'm creating a wiring diagram for those that are non-seq, have deleted all emissions (including charcoal canister), OMP, O2, and A/C. Pretty much leaving what the car needs to run (with aftermarket ECU and secondary fuel rail).

I need the mystery connectors in the pic identified: A, B, and C. Also if you see something wrong let me know.

Any help is much appreciated.

One of the two circled in red isn't there, not sure which each does though, so I don't know which one to remove from the pic.

P.S. (pretend the secondary injector clips look alike)

A looks like the O2 connection and C looks like the water level connetion

B is not there.

what is B then? C is not the water level connector, it is marked seperately in the pic (and the water level connector is white spade connector). C is a black single wire adapter (not a spade connector though).



is the attachment correct?

I think your off a little, A is for O2, B is IAT,IAT is idle air control, your knock is oil pressure, C is for knock sensor. Hope this helps.

The connector plug you have labeled IAT in the first picture in the first post is wrong, it is not the iat, it is the white connector plug for the Idle speed control (ISC), it is the only white plug in that wire harness. I know I am correct about this because I just looked at the harness and this white plug is the last plug on the harness before the throttle position sensor.

B looks to be the black connector plug for the AWS, the plug has one brown with yellow stripe wire, and a black with white stripe wire, the black plug with those wire colors is for the AWS, I am pretty sure it is labeled B in the picture.

C should then be for the IAT, the IAT black connector has a green wire and brown wire.

I know all this because I just got done removing all the aws stuff, emmissions stuff, double throttle and ISC yesterday, and now I can see the connectors and wire colors behind the UIM, and I know what they plug into.

ok I think i have it figure out except there is one extra plug. Are the two attached files correct?

I don't beleive the 02 connector is in the pictures, it is the only one wire connector up in that area so it should be obvious for anyone looking for it in person.

The A/C connector is not what you are thinking it may be in that 2nd picture above, I am not exactly sure what that is. It's not the A/C connector because there is a white connector just after coming out of a large wire harness down near the A/C and the a/c wire connects to the harness there and has another connector at the compressor.

I'm not using the 02 sensor thats why it's not in the pics. I've confirmed the IAT and all of that. I'm just unsure of the single wire that is labeled in blue in the black and white picture. It is a single insulated connector with a single light brown (may have been white at one time) wire goign to it. It also has like a mounting band attached to it. If this is for PS then I believe the diagram is complete and correct.

Just look at the pics in my most recent post above, they have been updated. Thanks

My last post was in reply to others (toddm) that replied, and I started typing it before your post at 12:29, so I didn't see your edited pictures yet.

I looked at my car and I can't tell exactly what the other wire is for, it looks like it could be for the power steering because of it's location, I see the connector but can't see where the wire goes to.

Sorry if this is a stupid question but what is CPS? I've never read anything about it or touched those connectors before, nor do I recall seeing where they go on the engine.

I need to be at my garage so I can look at the connectors on the PS and such. But I'm at school right now with only the harness with me. Thanks for trying to help with the limited information though guys, it's very much appreciated. When I get this completed I'll put it up somewhere with the wire colors also listed in the pic. And a write up for converting and rewrapping your harness.

crank position sensor(s), one plug is black and the other is white (that's why i shaded one of them in in the picture, so someone doesn't mix them up). They are the magnetic sensors behind the main pulley.

tom94RX-7

iTrader: (5)

thanks, I don't think I have ever seen those, I've never removed that pulley either.

4CN Air

iTrader: (7)

you can see them without removing the pulley, at first it seems like there wasn't enough room, but you can squeeze them out of there.

Ok I these two are correct, but one question: What sensor is beside the oil pressure sender? maybe water temp? it has a single male spade end. I'm wondering because I think the female spade connector in the diagram that is shown going to the oil pressure sender goes to this sensor instead. and then the oil pressure sendor connects to the sub-harness that the connects to the fuse boxes (and also the PS sensor).

Is this correct?

tom94RX-7

Are you sure about what you have marked as A/C? I remember the wire having two connectors, one connector was right at the large wire harness so if I remember right I was able to remove that whole wire from the harness and compressor.

You already have all the water temp sensors marked in your left picture, and I beleive that is the correct location, so the answer to your one question "maybe water temp?" should be no.

4CN Air

iTrader: (7)

well the A/C compressor has a single (white) male spade connector, and also the one in my pic has orange dots all along the wire which is also the case with the A/C wires coming from the drier lines. Maybe this coloring is used to denote A/C system components?

I've been looking at several wiring diagrams in various manuals and haven't found a good one yet that lists everything I need.


Also if all the water temp sensors are taken care of, my new question is what small brass sensor with a male spade end screws into the rear of the motor right beside the oil pressure sender?

Someone Please Help.

The sensor by the oil pressure is for the cabin coolant temp. With that plug disconnected the gauge will not read and the buzzer will be on.

4CN Air

iTrader: (7)

is that plug on the main engine harness or is it on the part that connects to the starter?

4CN Air

iTrader: (7)

actually if someone could take some pics of the drivers side of their engine it would really help me out. Like around where the PS pump and AC compressor connect and then back by the oil pressure sender and cabin coolant temp sensor. It might make things a lot easier for me.

Thanks.

I could take pics for you, everything is all together. is that what you want? a/c is removed, power steering not removed.

4CN Air

iTrader: (7)

yeah that would be great, everything around the driver's side up into the front of the engine even. Pretty much shots of the wiring as wide as you can to include the most reference points but close enough to look at wire colors if possible.

Thanks, anything would be a help.
