Reverse Light Wire

[JCode]

Can anyone advise the reverse light on my dash doesn't light up when im in reverse. Il ooked underneath and its just one wire from the bulb but looks like it goes into a harness where does that wire go to?  It would have to be going to power somewhere

Follow the black wire, if it's a factory installed light it should simply exit the firewall somewhere around the gas pedal/bulkhead are then plug into a single wire coming off the transmission harness near the bulkhead connector

I looked today I see the plug that comes out of the fire wall but the plug you show in the picture must of been cut because there's nothing there so im just gonna buy a new harness and hopefully it will work again, Thanks for all your helpmeet you know how it comes out
