Does anyone with a service manual happen to know where I can splice into a +5V Power Source?? I am in the process of installing my MAP Sensor and the instructions say it needs a +5V Power source not a 12V.
Thanks.

 

Noah, he is a map install write-up that a Harley guy did. I hope it helps.

1st step find a good location for install on 2/3 bar map sensor I installed the sensor on firewall on the driver side of firewall. trim some of insulation away a 2 inch /3 inch leaves room to bolt the sensor to the fire wall with two sheet metal screws. 2) step you need to tap 5 volts from a sensor I used one of the sensors that I deleted when I removed my egr the right and left wire were 5 volts and the center was a electronic ground I striped a bare spot and soldered the connection and raped with electric tape red to the 5 volt black to signal ground and the white lead add a length of wire and run it through the grommet in the firewall and solder it to ether of the outer pins one is analog 1 and the other is analog 2 the center wire is for switched 12v but in our app is not needed .3)step you must install a 1/8 on two sides and a 5/32 on the third side then you run a piece of rubber hose to the map sensor that way your factory boost gauge still works. 4) step is to set up the gauge first push both buttons at the same time and scroll through the menu till you find analog 1 if that is the one you used. First step is to ad the slope of 9.2 if using a 3 bar or 6 for a 2 bar map sensor next enter -14.7 for the intercept for both map sensor with engine off gauge should read 0
