stand alone 2bar to log boost... a while back, I installed a fuel pressure sender and wired it up w/ the stock EGR wiring in order to be able to log fp w/ EFILive...
these are the connections I made for the fp sender:
sender/pigtail to egr harness
Grey (gnd) to purple (gnd)
Blk (+5vdc) to grey (+5vdc)
Blue (0-5 signal) to brown (0-5 signal)
instead of using the wiring to log fp, I now want to use the EGR wiring to install a 2bar MAP sensor in order to be able to log boost w/ EFILive...
I am not running SD tune, so I need the stock MAP sensor to remain in place...
the 2bar map sensor's pigtail has a grey wire, a green wire and an orange w/ black stripe wire...
does anyone know which of the pigtail's wires to use w/ the gnd, w/ the +5vdc and w/ the 0-5 signal wires of the EGR wiring as listed above?

On the MAP sensor:
Pin A -- Ground
Pin B -- Sensor output
Pin C -- +5 volts
In case you need this as well for a calculated PID:
14.31psi / 29.01psi 4.90V
14.00psi / 28.70psi 4.84V
13.00psi / 27.70psi 4.67V
12.00psi / 26.70psi 4.50V
11.00psi / 25.70psi 4.33V
10.00psi / 24.70psi 4.16V
9.00psi / 23.70psi 3.99V
8.00psi / 22.70psi 3.82V
6.00psi / 20.70psi 3.47V
4.00psi / 18.70psi 3.13V
2.00psi / 16.70psi 2.79V
0.00psi / 14.70psi 2.45V
5.00inHg / 12.24psi 2.03V
10.00inHg / 9.78psi 1.61V
15.00inHg / 7.33psi 1.19V
20.00inHg / 4.87psi 0.77V
25.00inHg / 2.41psi 0.35V
29.10inHg / 0.40psi 0.02V
Pin A -- Ground
Pin B -- Sensor output

so...
MAP sensor pigtail to EGR harness
PIN A Orange/Blk (gnd) to Purple (gnd)
PIN C Grey (+5vdc) to Grey (+5vdc)
PIN B Green (0-5 signal) to Brown (0-5 signal)
now I need a custom PID to convert the voltage to psi

If you read through that thread you can figure it out for EFIlive, been a few years and I dont have the exact pid file anymore but you should be able to figure it out from there if they havent changed the software too much since then,
