Under the hood near the steering post should be a two prong (half male /half female) yellow and brown accessory plug. The heated shield kit has everything you need.The RCA jack wire (both sides male)is for the helmet.There is an Adapter wire (one side is 2 prong /other side is Female) RCA connector to hook to the sled.No splicing needed.
For my adapter i just loosened up my dash and slid it under neath it.It hangs out about 2 inches but doesn't hurt anything.
