Trunk Light Wiring Question

Shouldn't need to splice at all. The dome light connector has been in every Dart A Body I have had or worked on. Not sure on the Duster/Demon/Dart Sports though. It is where yellowdartdaave described. It will be yellow and pink wires. If this doesn't help let me know and I can post pics of mine. Also can you post a pic of the harness you bought?

Later,
