Hi, I have a 2005 Ranger XLT 4x4 with the 4.0L there is a blue plug that connects to the top center of the block and the lead wire is about 10 inches. Anyone know what this is and where I connect it? Just finished a rebuild.

 

thats not for the a/c compressor is it?

 

Thanks for your response. No the AC is located too far away for it to reach. Also all of the connectors for the AC are plugged in
