We’ve always suggested not to use wire taps when doing electrical work on your car.
The reason:
– They don’t always make a good solid connection
– Over time, with vibration, bumps, etc the connection can become unstable
Here is a photo of a Neon SRT4’s wiring under the dash that was part of the wiring harness.
An electrical wire tap was used in the security system and the tap severed about 90% of the wiring.
This in turn over time would create a intermittent connection and problems.
Now, granted, it appears that the person doing the job used the wrong size wire tap, which created this problem, but it further illustrates how these wire taps can create problems.
