I'm currently doing a Harrop/Dutch ECU conversion on a customers car and the postman has just dropped a T Map sensor off at my house (0281002437).  I wasn;t expecting it, but guess I am to fit it....

 

Plug doesn't match the current MAP sensor plug so I guess there's some rewiring to do....  Does anybody have details on what I'm looking for at this point as I've not had chance to look?

 

Cheers,

Instructions are in the manual for the OBDTuner software.

You will need a new plug Jim, let me know where you find a new one, I posted earlier looking for a source.

[NickB787]

I found an old Lambda plug which fits but I will need it.

[techieboy]

I've got 4 weird rectangular plugs on my Saab loom that look to be compatible. But, they might be too big given the limited space under the Harrop.

 

[NickB787]

I will fit as I had it on the z20let setup (just) can't lock it down though the Harrop holds it in place.

This is the proper version

[JimmyJamJerusalem]

Cheers for the info guys. 

 

I think this is the correct plug.  Just waiting to hear back from the seller to confirm

Looks about right. There seems to be plenty of different compatible versions out there, depending on the car manufacturers preferred supplier.

[JimmyJamJerusalem]

Hmmm, does anybody have any more information about wiring the TMAP sensor in....?

 

Looking at this pic I can't make any sense of it

 

 

Current MAP sensor connections are

 

A,  Black and brown

B,  Green

C,  Black and White

 

Not sure how to connect up stock connections into the New TMAP plug....?

[leevx2.2]

Cut the wires from the old stock conector if you look at t map sensor you will see the numbers 1 to 4 and conect wires to this as drawing black and brown to number 1 Black and white to number 3 Lt green to number 4 And then the same to the intake sensor plug Black in to number 1 splice it into wire Tan into number 2 job done

Last thing I promise.....

 

The IAT sensor connections are not

 

[*] - Black
[*] - Brown
[/list]

As stated above and in the drawings

 

They're 

 


[*] - Brown with black stripe
[*] - Brown
[/list]

Is it fair to assume the brown with black stripe is what you are referring to above?

 

[JimmyJamJerusalem]

Personally I think it may be the opposite...  Brown is used as a 'low referance' a few times in the circuit......?

 

IAT sensor

 

[Exmantaa]

Easy to check, as the 2 low references are probably connected together inside the ecu...

[JimmyJamJerusalem]

Oooh, sneaky sneaky, good thinking Frank, I'll bell it out and check it that way.

 

So looking at the A4  (the ecu), do you think there will be continuity across terminals 38, 39 and 22....?

 

Also would you think that would mean that these terminals are the low reference connector as that contradicts the bottom drawing.....  has anyone actually done this yet?

 

 

[Exmantaa]

I don't know the internal ecu pin layout, but just measure if 2 (low refrence) wires (map + iat) are connected to ground...

[JimmyJamJerusalem]

Right it was the other way around, brown is the low reference connection
 
I'm pretty sure this is right   even got some shameless advertising
 

 

[NickB787]

great just about to do this and I have

 

green+black

purple + black

 

ahhh

I think, as Peter says in his manual, the key is to forget about wire colours and do it all based on the positions of the pins in the connectors.
