Here's a way to keep your wiring harness neat and tidy.
Servicing anything in your car can be made into a hassle with the help of wiring. If you need to pull a panel off, often times there is a couple of wires holding it in. Also, have you ever had a gauge go out and it was a nightmare to replace because the 6 wires that go to it spread out into your car and are really difficult to replace?
A great solution is to make your harness easily disconnect. The nicest connectors out there were originally used in GM cars but now are used thought the aftermarket. These connectors are waterproof and come in many different sizes. MSD sells the connector housings in 1- 2- 3- 4- and 6-pin configurations. They are great for wiring gauge clusters with 1 connector as well as making branches of your main harness detectable.
