I bought a 1000 watt Conversion Kit Controller. It's got a purple wire that's labeled LCD Display and then there's also a Green Wire that's labeled Instruments. The LCD Display that I'm trying to hook up has 6 wires how am I to hook this up?

It might be for a special application, like some sort of scooter rather than a standard ebike one. You'd need to show us what it is with all the connectors and wires spread out so that we can see them and their colours. Did it come with an LCD? Normally, you need a matched pair for the comms to work.

The golden rule as mentioned above is to always source controllers and their matching displays together to avoid the inevitable communication problems attempting to match 2 dissimilar systems. The installed firmware can differ within a single brand, as many systems are 'personalised' with brand logo's and flash screens etc for customer brands ie yose etc. - a nightmare many of us have stumbled blind into before finding places like this ;)

displays will generally have:

1) a +ve battery voltage wire often coloured red,

2) a lock-signal wire often coloured blue, with SOME systems shorting this with the red +ve battery voltage in wire can start the controller headless with throttle control. - and could brick controllers not employing this feature..

3) a black ground -ve terminal,

4,5) a pair of Rx (receive) , and TX (transmit) wires, for communication of input settings and the display metrics, error codes etc.

6th wire??? Motor temp sensor? , Direct speed sensor input? lighting circuit? there are a few possibilities..

1000w while not usually the metric used to classify controllers (usually the peak amp output ie 15A, 20A etc is the metric more generally used . It suggests your bike? is outside the scope of this forum for specific advice ( pedelecs ie 250w max rated motor ..). For more general EV discussions with more specialist emoped e-m/cycle focused expertise the https://endless-sphere.com/sphere site could be more useful.

If i have misread the situation however and your just overamping your bike for kicks n giggles not limited by regs btw, or if its for a bike to ride on your own land wink wink,, feel free to post details and pics of your bike and problems..
