Bartt,
I have had Toyota's since 1979.
Go to ToyotaNation. There you will find a forum dedicated to the Tacoma. Search and you will find exactly how to change o2, A/F sensors.
There are 2 or 3 sensors depending on I4 or V6.
The upstream sensors are located in the exhaust manifold/s. These are actually A/F(air/fuel) sensors and directly feedback/control the fuel injector pulse length and timing.
They are easily changed. Hard part is getting to them. BUY the specialized o2 sensor socket it has a slot cut in it and makes changing them much easier.
Most people on TN swear by OEM or Denso sensors. Some have success with Bosche, others do not.
Do you have a code reader? If so it tells exactly which sensor is NG. Many auto parts stores will read your codes for free.
Feel free to email me directly if you need more info.

After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
