Isis wiring dilemma

[parsonsj]

I know some have used the power cells in soft start mode for headlights, cooling fans, etc and want some real world feedback as to whether that has worked out fine or been a problem.

It doesn't work fine. It works great! I used the ISIS kit on an LS3/4L80 69 Camaro with electric fans, A/C, headlight covers, halogen headlights, power windows, power locks, electric fuel pump, custom interior lighting, etc. I used two relays on the entire car (for the power locks, and only because the inMotion controller didn't have enough circuits).

Soft starting the fans works great... without the soft start, they would blow the 25A fuses. With the soft start, no worries, and I've tested the car extensively. I also used the inMotion controller to directly run the DSE electric headlight covers -- I didn't use the DSE controller. I also used the ISIS kit to control the A/C compressor and the heater control valve. The ECU sends the signal to the MasterCell, and PowerCell drives those devices.
