Wiring is routed out one end through a sealed and locked connector and two rotary dials to set rpm limit are positioned right on top--easier installation, super easy access and a clean, neat appearance under the hood. Controllers are supplied with wiring harness and components you need for install plus, vibration mounts. Increased output and proven multiple-spark power--MSD digital 6AL ignition controllers are a definite win-win!

Watch for differences when replacing old 6A

Summit RacingSummit Racing Verified Purchase

Aloha All, Replaced an old 6A (failed power lead as it would turn out, fixed and it is still working!). Not a drop in effort. 1. The case size different - Same length, however, it is wider (1/2" or so) this means having to drill out new holes and in my case move washer fluid bottle. 2. The leads now all go to one side (the bottom for me). This again, meant changing leads as they did not reach the new location as thy did before. Oh well, this is hot rodding!

It works!

Smoother idle, more power and better emissions. I have no complaints and easily passing CA smog is just a plus.

Bad MSD

Summit RacingSummit Racing Verified Purchase

Ordered two of these boxes.Neither one worked right out of the box.The original one I had (a year old)started overheating and shutting the car down.Spoke with MSD numerous times before they said that there were a batch of bad harnesses during the production run.Not Summits error but frustrating never the less.
