Sad MAP Problem
I cannot tell which wire on the MAP Sensor to cut into for the enhancer. Bought a Haynes manual for my vehichle, but does not show which wire goes from the sensor to the computer. I have a 2004 Dodge Dakota pickup with a 3.7 V6. Can anybody help? Thanks, Brad

If its a 3 wire like mine you have to splice into the signal wire. Assuming you know how to do that and all you need is what wire:

BE CAREFULL NOT TO SHORT/GROUND WIRES!!!
Take your volt meter and get a good ground with your black lead.
Turn your ignition key on.
With the positive lead from your meter, probe each of the three wires comming out of the sensor.
One will be +5 v. This is your sensor supply voltage
One will be 0.0. This is ground for your sensor.
And one will read less that 5 volts. This is the signal that goes to the ecu.

I would suggest disconnecting your battery before removing MAP harness and cutting signal wire.

Good Luck
