Connecting new work lights

[PostHarvest]

I know its the wrong time of year for this, but I want to upgrade the work lights on my JD 6220. But I'm having difficulty getting to the cable connectors. i don't seem to be able to get at them by taking out the head-lining. Do I have to take the cab roof off? Any help is much appreciated.

Yes, it's a roof off job as far as I know. But, when I replaced the rear work lights on mine, I opened the lamp unit, and connected the wires inside of it....
