Hooked up my scanner on a 92 ford explorer, V6, 4.0L, did an engine off check, got code 157. Replaced the mass air flow sensor, the pigtail to the mass air flow, the air filter, plugs and wires. Ran for a few minutes and hooked up the scanner again for an engine off test, now I get codes 157, & 159, seems like I have a wiring problem. Pulled the flow chart wiring diagrams, but don't have a breakout box. How would I get the 60 pin, pinout so that I can back probe this issue?

 

Use T pins... Philip

 

Ok, I don't know what that means, so let me give more detail about my problem. I bought this vehicle and was able to drive it about 10-15 miles before I parked it in the driveway. I have experienced a very rough idle(about 3K-4K) and once I started it up again, it wouldn't run on it's own, I had to give it gas for about 5 mins before it would run on it's own. So I hooked up my scanner as mentioned in my first post and then took the action(s) mentioned in my first post. That's when I got the second code, so everything I have found indicates that since I've already replaced the MAF, I'm down to tracing wires. So, I started with 159 since it was the newest code, I followed the steps all data shows, and have gotten to the first step for code 157, which requires testing pin 14 on my 60 pin connector. I need to know the pin out so that I can verify that I'm testing the right pin.
