MAP sensor wire?

By ballistic
- Tue Jun 02, 2009 2:49 am #120087 Ok, so I'm setting up my greddy blue box and I need to solder 2 wires to the map sensor wire going to the ECU, but in the place where it says this wire should be, there is no wire, here is the diagram I am looking at, maybe someone could shed some light as to what wire it is supposed to go to? :?

The 2 wires I am talking about are the green and white wires at the bottom.



Thanks

The wire that they say I am supposed to connect the green and white wire to it's the 3rd wire in on the 22pin connector on the top, they say that is the MAP sensor wire, I was wondering if maybe there is a different wire that is the MAP sensor wire, or if theres another way to wire this.


Thanks

and you're sure the directions are for your car?
Do you see the 2 wires they are pointing out anywhere else on that harness?
Do you have a helms or chiltons manual? I would compare with their wiring diagrams..

Yes, the directions are for the 92-95 civic EX's and everything else matches up perfectly to this point.

and no I do not have a helms/chilton manual, maybe someone could upload a pic or something of a diagram for this, that would be fantastic :)

The bolded one (D17 WHT MAP Map Signal) is the one I am talking about, could anyone put in english which wire this is on the actual harness?


Thanks, and sorry for acting like an idiot, I been so tired and I'm just trying to get this done with the least trouble possible.


EDIT:

I found this diagram
http://ff-squad.com/tech/wiring/wiring.92-95.jpg

and it says that D17 is the third one over on the top of the 22 pin clip, just like the Blue Box install manual says, but on my ECU clip I dont have a wire that goes to that part, will I have to get a clip thing and attach it to the ECU manually like that? or is there another way to do this?

- Wed Jun 03, 2009 3:05 am #120317 The blue box has two wires for the MAP sensor since it alters the signal. MAP in and MAP out. This is basically what the diagram is trying to show, they just aren't very clear.

It's the white wire on the second-biggest connector.

could this white wire be in a different location than the one that they state it should be in??

Thanks for the help
