Howdy gang!

I am upgrading my 1989 Wolfy headlights to the South African round lights. Can anyone tell me how to convert the electrical plugs from the late 80's rectangular lights to the SA quad grill setup with H4's? To my disappointment, the "kit" included no wiring or connections. I already have the correct "buckets" from an early 80's van. Do I have to make the connections from scratch? Yikes! Any help appreciated.

Thanks,
Josh
