Autometer Electronic Boost Gauge 12V Question
I have an Autometer Vac/Boost gauge (model#4777). In the installation instructions, it says to connect the 12+V wire to a power source that maintains power during engine crank. I just wanted to know what circuit anyone connected this gauge to or if waiting for calibration between ON and IGNITION would work around this (the installation sheet mentioned calibration errors if a constant power source was not used). Many thanks in advance.

Why not the Ignition wire? (blue with white or white with blue) Cant remember.. Under the dash above pedals.. (not under the steering column plastic trim)\
Cruise control circuit huh?? Do you own an evo? Cuz they dont have cruise control.

Even the gauge cluster gets power when the key is turned.

Was waiting to see if you figured that one out. Use the circuit going to the dash gauges. It is always on during key on. I used that with circuit tap to power my AutoMeter gauges and the Trustz dash overlays. IIRC used a 7 amp on the original side then a 5 amp to power the Trustz overlays and all three AutoMeter gauges including the electronic EGT gauge.
Since you asked, I do wait until the EGT does its cal after turning on the key, but I have tried it without the wait to cal and it does fine that way too.

Yes, I used to own an Evo (had 2 actually) and that is where I pulled power for my gauges. Just because they don't have cruise doesn't mean there isn't power in the fuse panel for it. Go look at the shop manual. Actually look at the interior fuse panel cover. It was labeled as cruise control on mine. It was just an empty circuit.
It is switched with the ignition and stays hot when cranking. Plus you don't have to splice into any wires and add any additional amperage draw to an already loaded circuit especially something like your ignition which is kind of important when there is one with nothing on it (because as sikrsix pointed out evo's don't have cruise) that's easy to get to but, what do I know.
