The sensor itself is clearly marked a b c ( Ive one sitting beside me )

There should be no reason to get it wrong.

Just looked at the DTA wiring schedule. Again it is very clearly marked a b c, and is correct.

Shouldnt really be any excuse to get it wrong.

Hit the wiring guy a slap lol

Hi,
yes now is very clear.... but in the moment I put the wires in the connector I talked with the guy sold me the connectors and I taked :

1=a
2=b
3=c

Mi mistake was not search a note for the map sensor...
Wen I try the different sens of wire, I tell you if now I have a correct values in the map
Thanks.

As the connector is marked...

a = a
b = b
c = c

lol...there is no reason to assume or deviate from that. DTA also listed them exactly the same way.

Well,
I put the wires in the correct pins and all run ok, now I must work in the map with the engine running.
After 30 kms I can say, I like very much read the air temp values, etc in the laptop and see the ignitions timming is working as I say in the first map.
Thanks for all !!
