b18 turbo Link 3 Bar map sensor- help needed!

[K20-DC5]

hi i have a dc2 teg turbo running an AEM ecu and Link 3 bar map sensor. the car used to boost fine at 1.5 bar until 1 day i accidently tugged a wire that was going from the Link 3 bar map sensor to the wiring plug of the original map sensor. the wire came apart and i dont know exactly which wire it was tapped into as all 3 wires in the plug are spliced.

there are 2 more wires comming from the Link map sensor- 1 is black and grounded to the body, the other is going into the loom Orange or yellow i think the colour is and there is a white wire that has come away from the wire from the map sensor plug(that i tugged).

i have tried to connect the white wire back individually to all 3 wires in the plug- when connected to 1 of them the car does not start, when connected to another 1 the idle is rough and the car misses and on the 3rd wire it seems to run ok but will not boost over 14psi.

any suggestions what it could be and how to resolve it?

if it only has 3 wires then it would be pretty easy to diagnose the problem.

1 wire will be logic ground (black as you said)
1 wire will be 5V positive
1 wire will be signal from the MAP sensor going to the ECU

if you are looking at the stock Honda MAP sensor from the top with the wires nearer to you, the pin-out would be ( + ) ( - ) ( signal )

do you have a way of datalogging the AEM? if you have it would be good to view what voltage you have regarding the MAP
