Save yourself the headache of trying to wire it up like the manuals tell you. Spend a little bit more up front and get a wiring harness kit from Painless, American Auto Wire, Ron Francis Wire Works, Centech, etc.
A 12 circuit basic Hot Rod kit will do. Call these people and tell them what you are doing. They are all very helpful.
These kits are VERY SIMPLE and complete. They will have everything required to do a premier job. Again, the companies are all helpful.
In the end, you’ll probably spend less than a do-it-yourself job following the manuals wiring schematics and end up with a great job.
DON’T BUY CHEAP…GET A GOOD HARNESS!!!
