71 Duster 360 turbo build

Well today was a bust. My water temp gauge broke when I was installing my cluster so I’ll have to order a new one, but for now I’ll just rely on the Microsquirt temp sensor. Next it was time to check for cam/crank sensor functionality which is when I learned I used the wrong wire to turn the Microsquirt on; key to start = power off. So I quickly rewired that to the brown wire off the column which…works? I tried the composite logger to track cam/crank events, but I got nothing. Checked power/ground at both sensors, and found loose pins on the cam sensor which got that working. However, it would only show up in the logger if I jumped the start solenoid; did not register when using the key to start even though the Microsquirt was powered up. The crank sensor(hall sensor sold by DIYAuTune) doesn’t seem to be working so I’ll take a closer look at the wiring for that tomorrow, but I followed the directions in the Microsquirt manual including the use of a pull-up resistor. Coils and everything else tested fine so I should be one sensor away from firing.
I struggled with this same problem on my MS install. There was simply too much voltage drop when trying to power everything from the ignition. So I power on my MS from a toggle switch that is constant power from battery (with a fuse of course) that feeds the relay that triggers the main "Switched 12V+ IN" on the MS. My MS unit also has separate/dedicated power and ground cables back to the battery along the passenger's side.
