I installed one of those pain-in-the-assess wiring harness. I had so many damn extra wires i couldnt use, took three months because i gutted the truck. Just go stock style and install as you remove that way you dont get confused where they route to. Also my friend took photos of the old harness in his car and used the polaroids to help run the wires right. Take your time to because wire burning smells bad. And dont leave you battery hook up. As you can tell ive had some bad experinces that i will never forget.
