1jz ELS Wiring... Demister and Light signals

[Z2TT]

I was about to say maybe it changes the Idle mixtures to help it idle stronger with the added load.

I haven't gotten to my wiring yet so i'll see how I go.

But the idea of using the A/C sense to get your engine to idle up for things like thermofans is good, just use a relay to send ground to the AC Pin on the JZ ECU (I take it most JZ ECU are ground for AC Sense)

Hi,

Just checked, both signals are active Low, so I take run the 2 wires together to trigger a relay that provides +12v to the 1j ELS Pin, and those 2 wires before twisting together run a diode on each so they don't trigger each overs functions, and have the diodes the other way around than on my first post. Would this be the way to go?
