Anyone know a place that sells all the sensors used by the 90-92 SD systems. I got a TPI system off from ebay and i need all the sensors and the wiring harness. I figured it would be easier to try and find a kit that includes all the sensors and gaskets. It sure would be a pain in the a$$ to buy each sensor individually. I mean how would I ever know what exactly i will need until i dig into the project. However my car is also my daily driver so I can't have it down for weeks at a time while im waiting to find parts and stuff. I read the Tech article about converting 90-92 camaro's to SD TPI, but i don't know how acurate the article is as far as its parts list. Can anyone help me here.

 

I go to a place I call the "Car Parts Store". These places usually list sensors by the year of car, make, model, and engine size. I have also found another place known as "The Junk Yard" very helpful. Any 4.3 L Blazer should have the Map sensor you are looking for ... The article is pretty accurate.
