4L80E shifter assembly wiring help please

[USCDOC]

I see 5 wires that exit the shifter. I am changing it for a 3L 80 shifter because I’m doing a 700R4 conversion. Three of the five wires fit perfect and match up to number stamps, but the other two I’m not sure what they go to. Can anybody help with this? Thank you!

Thanks, I’ve spent about an hour looking through those and various sources. I was hoping someone had a quick answer

Reverse light

Perhaps if you told us what year and what engine / transmission was in the vehicle originally it might help.
Also if you gave us the #'s you can identify it would help by elimination .
What shifter are you removing ? a 4 speed?
there will be a neutral safety switch, possibly even a switch for reverse lights.
All depends upon the wiring harness used in the truck

I guess I missed the Big title of 4L80e shifter.
But most likely for back-up lights

So apparently one is for the back light, and the other for the Park safety switch. The unit did not come with a reverse switch

A switch can be added to the 3L80 trans shifter.

Here are the 5 wires coming out of the shifter boot:

Wire #467 Backup Light switch

Wire #14 Neutral Safety Switch

Wire # 40 Shifter Legend
