 Any unused wires were simply...  Any unused wires were simply capped with a length of heat-shrink tubing. Heat the shrink tube, and squeeze the end shut with a pair of pliers for a weatherproof seal that will not short the circuit. |  Our completed wiring makes...  Our completed wiring makes the Classic Instruments cluster a plug-in, albeit a permanent one (who wants to go back to stock gauges now?). The wiring provided on the cluster is more than a foot long, making for easy wiring connections with the cluster out of the way, unlike the stock offering, which must be done almost by feel. |  The included instructions...  The included instructions explain in detail how to measure for the correct speed. Read your indicated speed on the included chart and follow it across to the proper dip switch orientation. Regardless of the type of gears, the tire size, or transmission type, you can easily calibrate the speedometer in a few simple steps. |
 After we were done, we discovered...  After we were done, we discovered this green-with-yellow-stripe wire was cut out of the connector and sealed off. Doing this prevented our interior lights from working, so we had to remove the cluster and connect these two wires-as they were in the original connector-for the dome lights to work again. |  After we finished the wiring...  After we finished the wiring and made some notes for the guys at Classic Instruments, we suggested offering a pigtail adapter to those who frown on cutting the stock dash harness. Classic Instruments happily obliged and will send this pigtail with all gauge kits. Now you can either use the company's original connector with your aftermarket dash wiring (such as a Painless harness), or if you have the stock wiring, you can use the included jumper pigtail to make the gauge cluster a plug-in for your stock wiring. How cool is that? |  With the cluster wired, the...  With the cluster wired, the speedometer calibrated, and everything else double-checked, it's time to secure the new gauge cluster into the dash of our '68 and reassemble the heater controls and steering wheel. |

Since our installation was based on a preproduction prototype, we want to detail exactly what you get when you open the Classic Instruments box.
