you can easily mod a stock one to work with a 350x headlight. i did it on mine. your idea should work fine ill check out my harness after school and let you know. i was going to do this but for some reason i thought there was some type of connecter you needed i dont remember. ill check my harness out wile i still have it and let you know. but yes the srink wrap or this stuff i have looks pretty clean ill get some pics to show you.
