ISIS – Intelligent Multiplex System???
 

After reading posts by L & H Kustoms, reboot04 and researching the ISIS website, I am debating whether or not to go with the ISIS system instead of a traditional wiring harness.

The pro’s of the system seem to be reduced time / labor for installation, reduction in number of wires, the flexibility to add additional circuits, reduced weight, and its programmable. There’s even a key FOB that will allow you to turn on the parking lights, headlights, instrument panel, 4- way flashers, cooling fan override, panic switch, ignition and enable / disable the car.

Cons - The initial price… but it could equal out if it takes less time to install.

Does anyone else have experience with the Multiplex system? Any thoughts?

Thanks for the help,

Good post. I was debating this same thing. Tyler @ ATS had good things to say about it. Maybe he will chime in...

I hope Tyle does chime in as I value is imput, here is mine, and I will say I don't have any experince with the product and I am just as interested as anybody.
But it looks to me that you will need the 3 cell unit @ 999.00 for a street car and many race cars as each unit has only 10 fused circuits. And for them to say that you can cut your wiring time in half, I don't see it as you still have to wire the same number of systems. Also the real time in wiring a car is layout, routing and terminating, anyone can just throw some wires into a car and make things work, the real trick is to run the wiring were it is servicable, functional and looks good, thats the time. FYI I'm not the wiring guys in the shop but I do work with them.

Don't forget documentation. When doing something totally different like that, you have to produce your own as-built wiring schematics with termination diagrams. (Unless ISIS gives you generic schematics?)

I have looked into this as well. My concern is trouble shooting down the road. What happens if something in one of the "boxes" goes bad? With a standard system, you can trouble shoot with some wire and a light bulb from your tail light if needed. This system relies on technology only seen in OEM and industrial applications. You may not find a controls engineer in the middle of the power tour when your lights don't work. Just my thoughts. I would love to hear feedback from someone with actual experience as well.

I was also concerned about troubleshooting issues…but after some research I found that it does have an optional “diagnostic module” that helps you diagnose and troubleshoot the system. The module has a 4-line high intensity blue display. If it performs as advertised, it sure beats the old school way of troubleshooting

I'm going to try to set up a video interview with these guys at SEMA and get some of these questions answered... it's a very cool system and I'm intrigued as hell.

This is like the F1 car of wiring harnesses. Diagnostics are stupid simple as is the actual wiring of the vehicle. I'd recommend this to anyone who needs a chassis harness; it is the best, most advanced and simple install you will ever do when rewiring a vehicle.

Isis for life!

That's very cool. It's not really clear, though. As I understand it, it replaces the body control wiring, but has nothing to do with engine management, correct?

Sounds interesting, I'll have to check it out at SEMA.

Looking at the details on their website, everything is pretty straight forward. But how do you integrate turn signal/brake lights/running light into this system?
