Police Body Cam had wire ripped out

[Doc38343]

I got this in trying to help my local police dept save a couple of tax dollars.
Officer was in an altercation and the suspect ripped his body camera off his shirt. It pulled loose the wires and I soldered it back on but i need to be sure they are correct in position.
Red = tip
Blue = 2nd from tip
Yellow = 3rd from tip
(The officer thinks that is right he had opened it and they tried to re-attach)

4th from tip goes to ground AND there is a mic but it is glue sealed so i can't tell if it runs back to the cam or just to the DVR that attaches to their belt. I think the wires are Audio, video, power and ground.
No brand name but WAY over priced in my opinion. Therefore I'm trying to fix it for them.

best way might be to get the officer's "friend" (ie. partner) unit, remove the cover and do a resistance / continuity measurement back towards the end

if there is no power there nothing should be harmed by trying it .
wires look right to me .

I'll get him to stop by. There are no shorts I just wish we were sure. It does get 3v from somewhere to run the 25X40CL memory chip and the oscillator. Other side of the board just has the video sensor and 5 or 6 caps. (I don't want to get it dirty) I tried to follow the VCC in reverse but the solder mask is just to thick and the parts too tight. They consider it a loss anyway so I'm for trying it.
