need help for wiring up a gm 3 bar map sensor
If you want to know the wiring for a GM 3 Bar Map (can run up to 29 PSI)
BTW this is for an OBD1 Wiring Harness
A- goes to the Green and White wire which is ground
B- goes to the white with a yellow stripe which is the map signal
C- goes to the yellow with a white stripe which is the 5V Power
BTW this is for an OBD2 Wiring Harness
A- goes to the Green and White wire which is ground
B- goes to the red with a green stripe which is the map signal
C- goes to the yellow with a red stripe which is the 5V Power
Just a word for the wise:
GM 3 BAR MAP will work with Hondata but you need to have your datalogger set to GM 3 BAR MAP Voltage because the GM sensor runs on a different voltage than the stock Honda sensor. What I did with mine since I do not yet have datalogging is I grafted in the GM 3 BAR MAP onto my stock harness and then I will switch which MAP is plugged in when I go to get my motor tuned. This way I can run my stock one for now and then just unplug it and plug in the 3 bar when I go to get it tuned. Also if I ever want to sell the car but keep my 3 bar and Hondata I can just plug in the old MAP sensor
