Emergency Shut-off feature
The Digital Delay Mega Switch Panel has a unique and, in my opinion, a feature we have needed for a long time, an Emergency Shut-off. When this circuit is wired to a switch (in our case we are going to put it on the steering wheel) it disables the entire relay board with the exception of the tail-light. That way if you have problems at a night race the track safety crew can still see the tail-light even if you have shut the entire system off. This is one of those ideas that could save your life. No fumbling for the ignition switch if the throttle sticks or fuel leak, etc. Hit conveniently located Emergency Switch and the entire electrical system and ignition is shut down.
Pre-planning will save you a lot of trouble later.
I realize this little bit of information should not surprise those of you who have rewired a car before, but, if this is your first time, get out the pencil and paper. I recommend you make a list of what the wiring needs to do for your race car. Make a list, make a sketch or whatever works for you to help you see what accessories you need power for and how you want to route the wires to those items. The Digital Delay Wiring Kit simplifies a lot of this because their circuit board includes fuses, relays and labeled connection points for your accessory items. How and where you run the wires will be up to you but preplanning is the key to success and will prevent a lot of frustration. Digital Delay provides a great-looking schematic that provides wire colors and what that wire is intended to power for your car.

| This is our switch panel as viewed from the outside of the car with the body panels removed. It works, but when I get it this far apart I sometimes wonder why. | This angle shows how the wires currently arrive at the terminal strips, ignition and go to the gauges and delay box. |
 |
| This is the driver's view of the current switch panel. The ISP poured seat limits elbow room because it supports my ribs so well it is difficult to reach the switches. It is something I wanted to change and now is a perfect opportunity. |
Now the work begins, removing the old stuff.
I hate to miss this part of the operation but I will be on the road and away from home most of the winter. This means my son, Andy, is going to do the removal and the rewiring. He is all set and is ready to get started. This will be the first tech article on Project 4-Link that I didn’t actually take part in. Sort of strange but Andy is very meticulous and as you will see, can produce a great finished product.
One other project that has to be completed before the rewiring starts is the design and fabrication of a new dash panel. We are eliminating some of the gauges and I want the Digital Delay Mega Switch Panel to be on the dash. This switch panel also will control the LED Mega Dial-in Board we will mount on the dragster scoop. More details as installation begins.
Keep an eye on these pages as we should have the rewiring finished up by the next issue.
