2G 97 transmission sensor (Reverse Switch)

[954g63gst]

I have a 97 gst. The transmission has this sensor with the harness plug. The harness plug is cut 6” away from the harness connector. Where do I splice it back to.I can’t find the wire on the harness tha comes from the passenger side firewall.

Is that the backup light switch? That is what it looks like in the picture. If it is, it just makes a connection to turn on the reverse lights.

There is no other end to hook it back up. if I can see where it goes, I can make the connection. I just need help finding the right place to put those two wires to. Any help please and thank you

I don't have any 2g's anymore but I will see if I can find the wire colors. If it is like a 1g, the wires will be in with the loom that has the MAF connector on it but it is way back in the loom, so probably hiding from you, being cut off like they are. (Pet peeve of mine to hack off a good connector)

Here ya go. Looks to be Red with a blue stripe and Black with a white stripe.

Ok so I found where it goes the guy soldered the wires together for I don’t know what reason. My pigtail is from a different year I assume. Should I just hook both red with blue stripe to white with blue stripe and then hook both black with red stripe to black with blue stripe

That will work. You can test it pretty easily before soldering, or using crimp connectors. The electrical sensor on the transmission that is plugging into, is what engages your reverse tail lights when you shift into reverse. With it not connected, it will simply not engage the reverse lights.

Do you have any way to check for voltage on either pin/wire on the body harness, like a volt meter or digital multi meter? I would look for voltage first just to see that there isn't any, then go from there. The backup light switch only makes a connection to ground for the lights to come on so at least one wire should be a ground wire. I wouldn't want you tying into a wire that is "hot" with a switched ground. It would definitely blow a fuse.

Not at the moment. I am in the middle of relocating the battery to the trunk. I will check tomorrow once I finish the battery. Thanks guys.
