The breakout box
Used just for the ignorant chit
There were different inlays for different cars doing different tests and it was a head scratcher at times
Taught us to just back probe the sensor connectors and processor to essentially test the same circuit
If you have a TP sensor code, I am damn sure not hooking up the box to test it
But that is Fords way. Install breakout box and measure the vref and signal return
1996 and newer the box has 105 pins instead of 60 (EEC5)
