## Questions & Answers

**Q: Is there a list of what circuits are included? For example , headlights, turn signals, dome light, trunk light, wipers, lighter.... so forth? Thanks**
A: Yes it comes with a small booklet that explains everything in detail. Further, each wire is also labeled like headlight+ or headlight -. It allows for wires to be added or taken away. Walks you thru step by step. It is still helpful to get the schematic and color coding for your vehicle as this is generic. It allows for major American makes. Your particular model may use a different size wire for some parts like sensors. The kit is size 14 but like some models sensors use 18 or 20. So do your homework and get a couple spools of wire for them. The biggest safety item is to disconnect the battery completely, negative and positive! If you get stuck send another question out to me.

**Q: Are the wires copper core wires?
or aluminum wire?**
A: All wiring is copper.

**Q: 2,3 ford long block motor**
A: works great and ends are marked  perfectly

**Q: what is length of front and length of rear of wires extended from fuse box?**
A: front is 6 foot back is about 10 ft
