testing an A9L

go to technical and then O2 sensor harness ID for re-pinning, helped me out alot

If it is original, the capacitors may be on the edge of deteriorating by now anyway. When I swapped my Ditzy original computer for a Local salvage yard one, I sent the Ditzy one in for a re-cap and test. It was not very expensive, and tested out fine after the standard fixes. It is waiting for use and should be ready to go if or ever I need it.

How do I re-pin the auto trans harness (A9P) for use with and A9L. In other words, If I want to put and A9L in a car originally equipped with A9P, how do I modify the O2 harness?

If you’re looking what to re-pin, it’s based on your car, harness, ECM, trans, year, etc. well need more details or you can google as others have mentioned.

Assuming you know what to change, the mechanics of how to re-pin are actually pretty simple:

On the O2 harness 8 pin connector, look at the pins and you’ll see a red piece of plastic. This ‘locks’ the pins/wire into the connector. This red piece slides in and out by taking a straight pick (or hard nail, in a pinch) and pushing the red tab on the side of the connector (not in the valley where the pins are, rather the side of the connector itself). It’s sort of an in-and-up motion. It doesn’t take much, so if you’re feeling like you’re trying too hard, you are.

Once the red tab is out, the pins won’t simply fall out - they are loosely held in with tabs near where the red plastic piece resides (each pin has a tab holding it in, these are in the valley where the pins can be seen). Gently move each tab for each pin you want to remove (be VERY gentle. It only takes about the thickness of the pick to release the pin) and the pin will simply fall out.

To re-pin, just push the wire crimp into the correct hole on the plastic electrical connector. You’ll hear/feel a faint snap that holds it in place. Put the red piece of plastic back in to lock it all up and and you’re done.
