*If you are in cold temps I would highly reccommend Braid. I will remain soft and flexible to work with.
 
Here is a fresh new wiring harness for your 87-90 Suzuki LT500R.
OEM matching colors
Matching OEM style connectors for plug and play operation
Constructed with quality materials 
Proudly made here in the USA in my own home using my own 2 hands.
Hi/low beam
stock light switch
key
tail light
plug it in and go.
* I have removed one ground ring from the harness for a cleaner look. If you compare side by side to yours, you will see one is missing. As long as your frame is clean you will be good to go. Factory includes an alternate ground in the event one becomes dirty. if you want both grounds just shoot me a message.
