S60R & M66 swapped XC70. Last Few Issues...

[Tumbler510]

I am finally nearly done with my S60R & M66 swap into my XC70, and I have 2 outstanding issues that I am having trouble finding any info for online. Any help would be greatly appreciated!

1. Reverse lights. The reverse switch on the M66 is not connected to anything, and I can't find any connector from the OEM auto trans that looks like it would hook up. Can someone guide me in the direction of wiring in the reverse lights to this switch?

2. The backup sensor "beep" from the rear right door is on all the time when the ignition is on. I tried moving the shifter around to all positions, and it stays on steadily. I wired in something in the shifter (it was so long ago I am trying to remember), and I am usually correct in my wiring, but wanted to see if anyone can point me towards how to Troubleshoot this issue.

Thanks a ton for any help!

PFA before the swap. Hoping to get it back out on the trails this summer and get more footage from the adventures!

I figured it out while talking to a Volvo buddy, and it's a lot more simple than I imagined. I'll leave the post incase anyone comes across it in the future.

Note: I was asked to check the reverse lights on the car when the beeping was occurring. The reverse lights were on 100% of the time.

Both the reverse lights and the backup beeping (sensors) run through the reverse switch on the transmission. When the car was running with the OEM automatic, I shorted a connection to ground to bypass the start inhibitor initially. I left the short there, and after the tune was flashed, the above 2 issues started immediately. It's because that same circuit on the MANUAL car is the reverse switch circuit. I just went out to the car, removed the ground, and the beeping went away immediately, and the reverse lights went off. Now I have to make a connector for the reverse switch, wire it in, and its good to go.
