Ok I uploaded the Wiring Diagrams for the Engine Performance for the L Engine (I can’t find anything on the I don’t think they used.
How To Discover If You Have Wideband Or Narrowband O2 Sensors NOTE: MOST poor results can be traced to an incorrect installation of the EFIE using the wrong sensor wire- The sensor can have 2, 3 or 4 wires (some can have 5 or 6- these are rare), and present in a few Chrysler/Dodge/Plymouth & Jeep models. The two white wires are for the sensor heater and do not matter.

Btw – 87 did not have 4 wire sensors, starting in 88 did Toyota use 4 wire sensors. What I do remember is the following: The Blue is signal + (the original o2 wire). Let’s take a Dodge Ram L, for example.
By looking at the wiring diagrams (see Figures 5 and 6 for wiring diagrams provided by Mitchell 1 ProDemand), we can figure out which wires belong to the oxygen sensor heater circuit by simply matching wire colors. There are 4 wires on the oxygen sensor of my Dodge Ram truck.
