Wiring

One are that teams really struggle with is the wiring harness. So we paid special attention to create a well throughout and executed harness. We tried to create a harness that looks professional, something that looks better then you would find in your own cars. For this we used a high temp braided sleeve that the wires were covered with. To secure the sleeve we used a combination of self vulcanizing tape and adhesive lined shrink tubing. Here are the results.



One feature that is unique is the use of a bulkhead connector. This connector acts as a through connector into the electronics box eliminating the possibility of wires chafing on the edges of a grommeted hole. It also make engine removal very simple. To disconnect the wiring system you disconnect the bulkhead connector, starter and alternator, and as far as the wiring goes... your done.

Where the harness split into different areas we would use shrink tubing. On one side it would be a single large bundle, on the other it would split into multiple harnesses. To take this harness one step further you could use pre-molded harness "T"s and "Y"s. Also before covering the wire with the braided sleeve you could cover the bundled wires with heat shrink. This would give the harness a nice black look and really seal out all of the elements. However, what we have achieved here is far superior to previous years and the majority of the cars I've seen at the competition.
