1n gives me battery voltage... Dont want to waste another 50
Can i hook up to any source that is lower than 5v? say 1.010v or .853v? As long as its no higher than 5 i should be okay right?

Can anyone show me exactly what wire they tapped into? I found a wire that was 5v i thought but once i soldered and turned on the car it read battery voltage, I shut it off within 2 seconds of giving it power.

Look at the MegaSquirt PnP Manual under the section on adding a variable TPS.
Note that there is a pad on the daughterboard called "5V Vref". This is the fused +5 supply that you'd normally use to power a variable TPS. You can connect this pad to an unused pin on the middle connector and then access it externally. The pinout of the center connector is listed in section two of the instructions.
Now tell us what you're doing with an external MAP sensor on an MSPnP.
