Normally with all the accessories you are activating with the switches on the Mega Switch panel there would be a big thick bundle of wires, right? Well, think again. On the Mega Switch panel they use very small wires from the switches to the Power/Circuit board. The Mega Switch panel comes with a pre-wired small (about 3/8” diameter) cable that plugs into the circuit board and that is all there is to hooking the switch panel to the Power/Circuit board. This makes wiring from each switch to relay or fuse panel a non-issue since Digital Delay did all that for you.

We ran our wires down both sides of the chassis and held them in place with P-fasteners that we riveted to the frame rails where we could. My suggestion is to run all the wires where you think you want them, sit back and think about it again, then finish them up.

The Mega-Dial Board is a cool option. If you order the Mega Switch panel with the Dial Board option it is all on the same panel. You can change dial in with one finger, from the seat of the car and lock the display in a matter of seconds. (Now, if I could just quit changing my mind about the dial-in every two minutes while I am in the staging lanes!)

We use Weather-Pack connectors on our electrical items so changing them out is easier and moisture becomes a non-issue. You can get these connectors at most electrical stores or through performance mail-order outlets. You will need to buy a special crimping tool but the expense, in my opinion, is a bargain for the quality connections you end up with.

We use a 16-volt battery and no alternator on Project 4-Link. This means we have very little chance of electrical interference and all the Digital Delay products are 16-volt compatible.

If you are wiring a race car, chances are it is not your first time working with automotive wiring. It takes patience, good tools and top quality products to end up with a trouble-free wiring system. In my opinion Digital Delay has produced a top quality product from start to finish.

This is the schematic drawing that I used to wire Project 4-Link. Nothing beats a simple-to-understand drawing for me. Color-coded wires are supplied and it made the task much easier.
