I am replacing my 4 wire oxygen sensor on my ''''93 Rodeo 3.2 ltr. with a universal one. My original one has 2 black wires, 1 blue, &amp; 1 white wire. I need to know which are heater wires, signal wire, &amp; ground. The universal sensor is color coded differently. Thanks for help. <! Message ''''"" >

 

The 2 black ones are the heater wires. The White is the ground, and the blue is the Positive wire.


You know why nobody responds?... because nobody on this forum knows anything about cars. Dor yourself a favor and find a new forum.Edited by: Nick6147
