New to working on Jeeps, and a kinda stupid question... I just welded in new floor pans for somebody, into a 94 sport, and took it for a drive only to find that the radio and fan weren't working. Several plugs were not plugged in when I started, but I neglected to mark any of them.

In the photo, the lower bigger plug was on the side of the heater output to the rear seats, in front of the shifter, and I think it was not plugged in. The smaller I thought was plugged in, but I can't for the life of me find anything free in the area, much less anything that would fit it! Tearing my hair out over this ridiculous little thing, but I can't give back a Jeep with no fan or radio. Anyone have any idea which plug the power to the radio and fan runs through, and where the wire leading to it originates?? Huge thanks in advance for any help!
