ISIS Power and Spaghetti Engineering Digi-Tails

[Turbo67camaro]

I was confused trying to figure out how to wire Spaghetti Engineering Digi-Tails sequential LED tail lights with the ISIS Power system, so I called ISIS, and Jay Harris gave me the low down.

Example: for 67 Camaro LED Sequential Digi-Tails (standard, non-RS rear tail lights)

Jay - In short, follow the Single-Filament ISIS schematic instructions, NOT the Multi-filament instructions in the ISIS documentation.

How does the ISIS system tell if your system should run in the Single-Filament or Multi-Filament mode? Jay - It does so based on how the inputs are wired to the Mastercell !

Wire mapping
===========================================
ISIS Yellow wire -> Digi-Tails brown Rear Running Lights
ISIS Brown wire -> Digi-Tails yellow Left Rear Turn Signal
ISIS Violet wire -> Digi-Tails green Right Rear Turn Signal

When the brake pedal is pressed, ISIS will send power to all three of the above wires, turning on the brake lights.

I've not tested this yet, so hopefully it works as described and expected.

I anticipate that if you have Digi-Tails for a different vehicle that has virtually the same Digi-Tails wiring schematic, the ISIS wire mapping would conceptually be the same or very similar.

are you happy with the ISIS system and did you install it yourself ?

I'm in the process of installing it myself, albeit slowly as work keeps me pretty busy.

Being a software engineer, I'm happy with it. It makes a lot more sense to me than old school wiring lol.

Eventually I hope to get time to build some custom software applications to work in conjunction with it. Nearly all electrical controls will be accessible via an IPAD or Android tablet. I'll add some standard switches for basic stuff like headlights, wipers, push button start, but I expect to keep standard switches to a minimum.

The one thing I'd REALLY like to see, that I don't think is available yet, is documentation on the software interfaces used by inTOUCH NET, to be able to customize the web user interface. I think at the moment I'm limited to using their web user interface to access the virtual switches and controls. I'd rather program that user interface myself. Once I start playing with it, I'll see if I can reverse engineer the web interfaces and write my own user interface wrapper around, or bypassing their user interface.

Any update on the wiring? I am getting ready to wire my digi-tails up to my ISIS system. The digi-tails diagram has the wires combining before going into the stock harness. If I understand correctly, there would only be 3 wires used on each tail light (ground, power, and signal to ISIS (LH brown, RH violet)). Is this your understanding?
