Project 240SX Land Speed Racer Wiring

The Road to Speed Week 2014 Part 3: Gettin' Wired With Zombie Vampire!

by Joe Lu 

The countdown to Speed Week is well underway, which means that pretty much everything becomes secondary to getting the car put back together.  One of the most important additions to Project 240SX LSR this year is the new wire harness, the sole informational network responsible for making sure that the car is able to operate to its full potential, and also do it reliably.  As covered in a previous update, the old wire harness which was completed as the car was literally being loaded on the trailer accomplished the goal of getting the car to the salt. However, we knew that it would need to be upgraded in the interest of reliability for future seasons.  Well, the future is now, and the new wire harness is built to perform.  

The benefits of having a proper motorsports grade wire harness are numerous, from having reliability enhancing, continuous leads from end to end, high levels of durability from the almost-everything-proof Raychem DR25 outer jacketing, lightweight and chemical/abrasion resistant aerospace grade Tefzel wiring, in addition to the use of water/dust/salt resistant circular connectors and Deutsch DTM connectors.  The combined benefits of each of these components will no doubt come in handy under the harsh conditions of the Bonneville salt.  The harness also looks a heck of a lot nicer than the yards of exposed wiring that used to run throughout the car.

Of course, quality materials are only as good as their assembly. With that being said, let's take a closer look at how the harness for Project 240SX LSR was painstakingly constructed, lead by lead by our resident Zombie Vampire extraordinaire, Nick Hunter, 5523 Motorsports' Jen-Bot and Zombie buddy Evan Dunham (+ dog Zeus). 

Planning is everything. Here, Nick and Jen-Bot record the functions of each individual wire.  These notes will be key in creating wiring schematics for the entire harness later on down the line. Wiring schematics?! I think someone's race car just leveled up!

MotoIQ race car or SpaceX project?  Whatever the case, this harness is the bees-knees.  Note that zip ties are only used to form the harness up and hold everything together prior to final assembly.

Straigt-up aircraft grade goodness! I used to deal with this stuff on a daily basis. It's legit, as is the multi-jillion dollar war machine analogy. I assume the "cherry tape" you refer to is silicone tape, AKA F-4 tape. Only sticks to itself, smells kinda yummy, is also super expensive.

That's the stuff! Looks like a roll of black bubble tape gum, stretchy, and once it makes contact with itself, is darn near impossible to peel back apart, it has also been used in the engine bay to protect unused harness connectors from the elements.
