I need to know which wire from the MAP sensor to the ECU I would tie into to install a ''MAP sensor enhacer'' for a HHO system? Would it be the Yellow wire or the Green with red tracer? It on a 1995 Toyota Corolla?

P0105 = Manifold Absolute Pressure Sensor Circuit Malfunction I assume the code will not clear when you try to erase it? Either the circuit (wiring) is damaged, or the ECU memory won't reset/erase the code. If you know the wiring & MAP sensor are ok, try zero-ing the electrical system (disconnect the negative battery cable and connect a wire to the negative battery cable & connect the other end of the wire to the positive battery cable for 30 seconds. Remove the wire & reconnect the negative battery cable to the negative battery post. Now, this shoud have erased the memory in the ECU and there should be no code(s) present. If the code is still there, (and there's nothing wrong with the wiring between the MAP sensor & the ECU), the ECU is faulty.
the hho generator power and ground does not go to the maf sensor. what you need is a maf /map regulator, but it has no connection with the generator. it is just helpfull by saving gas if a hho generator is installed. If you have o2 sensors in the exhaust pipe, you need a EFIE first!!! more questions, no problem, firstname.lastname@example.org, greetings, ****
MAP enhancers usually wont do the trick for long - the computer will learn the adjustment to the MAF and overide within a day or so usually less than a few minutes.
The computer is best altered using an EFIE to adjust the O2 sensor(s), usually adding between .2 and .3 volts to the O2 sensor signals does the trick - each combo of the HHO and car is slightly different - you have to play with it to find your best setting. You only need to alter the signal on the O2 sensors ahead of the cats as they are the ones the computer uses to adjust the fuel.
Well after looking it up it's the the map input wire is light green on both 4 and 6 cylinder models.
On a 4cyl the map has black gray and light green, the black is ground, the gray is a 5 volt refrence from the pcm(power control module), and the light green goes to to ECU for MAP input.
On a 6cyl the map has black gray and light green, the black is goes to the automatic transmission, gray is a 5 volt refrence from the pcm(power control module), and the light green goes to to ECU for MAP input.
