im doing the l92 head/ ls3 intake swap onto an lq4. i ordered the ls3 map sensor and the pigtail to make it work. i want to make sure this is the correct wiring for the ls3 map:
LS3:
Pin 1 - 5 volts - gray
Pin 2 - Ground (low reference) - orange/black
Pin 3 - Signal to PCM - light green

just making sure because the colors of the wires are exact same as the ls1. even the voltages match up. also if i am holding the map in hand and looking at the pins, which one is pin 1?

 

I am pretty sure all three wires on the pig tail are going to be white. Or at least from the dealer (ac delco) so you won't be able to just color match them up. At least the two pig tails I bought from them were.

 

Here is the schematic

Looking into the sensor, left pin is output voltage, center is ground, right is supply voltage

 

thank you, thats what i needed.
