Hey everyone. I'm trying to T-Tap into 3 different wires so I can monitor the signals using a computer. However I need to know which wires are which in each case:

1) The MAP sensor: This is a 2-wire harness. I assume it's either signal + ground or maybe signal + signal (where the voltage ratio determines the MAP). In any case, can someone tell me which wire to tap and what color it is? I want the wire whose voltage expresses the manifold pressure as far as the ECU is concerned.

2) The TPS sensor: There is a 6? wire bundle coming from the throttle body and one of them is rumored to be a 0-5V reference that tells you the throttle position. Again, which colored wire is this in the bundle?

3) The Knock sensor: There are 2 knock sensors that I am aware of, one for each bank. I only really need 1 of them. The ECU's X2 (the grey) connector has 4 wires that pertain to the knock sensors, 2 for each sensor. However I can't find a detailed description of each of the 2 wires so I don't know which is ground or 5V or whatever. I want the wire that has the acoustic waveform on it that goes to the ECU. Anyone know the pin number or color of that?

Please help me if you know any of these. Thank you.
