I stretched some female connectors to my ECM by front probing. You have to be really careful and mindful of your probe size vs. the female size. My ECM connector is on a 37 year old Porsche 944 and they deformed easily. Back probing is likely better in most cases, maybe not 100% of cases, but most. Also, there are many newer modern automotive connectors with tiny females and almost any probe can deform them by front-probing. People be aware of this as a possible issue -- damaging connectors.

Never use to big of a pin and force it in. It should take very little pressure to slide the pin in to back probe. When you front probe the wire, if the pin does not fit, find one that does. That should have very little resistance to insert to test. If you use to big of a pin, you can expand the electrical connector which can cause pin fit issues.

Front-probing with a T-pin! Yikes! Not a good way to check for voltage at the pins. I've fixed quite a few terminals that were spread open by other technicians. I recommend finding the male terminal of the same size with a short length of wire to clamp the alligator clip to. Better yet, just stick with back-probing with a T-pin.

@@FixyourNissan yeah, but consider the fact that T-pins are not designed or manufactured to the specification of the terminals. If they are too big, they will over stress the terminal, making it loose. If they are too small they will just slide out when clipping your alligator clip to them. Also, the ends of the T-pins can become bent from use or can easily tilt in the female terminal simply from the weight of the alligator clip and lead, again causing excessive strain on the terminal and making it loose. In fact, I noticed the T-pin in your video is bent at the end. There are a couple of other reasons I prefer not to front probe, namely, front probing means you've disconnected the connector and if you are checking for voltage, you'll simply be checking open circuit voltage. Most diagnostics are better performed by performing a voltage drop test or an available voltage test with current flowing. That way any resistance in the circuit will show up during diagnosis. One can argue, that a check with an ohmmeter can be performed to check for resistance, but what if the terminal you are probing from is the cause of the excessive resistance because it is a spread terminal. You'd never know it by front probing with a T-pin; or what if a wire has broken strands and still has a couple of strands touching. The low voltage from the ohmmeter may not be enough to heat the wire causing excessive resistance like it might when the full 12V is applied and normal current tries to flow through the circuit. One other item to think about, whenever I front probe, I try to use a terminal of the same size or a tool like OTCs terminal test kit (No. 3587). That allows the terminal tension to be checked while testing with a DMM.
