I'm looking to sell my HSI. I did miss taking the photo until after the converter and slaving accessory had been disconnected, so it's not showing needle deflection. However it is working. I believe I can get the complete wiring harness out without cutting it. PM if interested.

It consists of:
331A-G course Indicator (photo attached)
323A-G Flux Detector
332E-4 Directional Gyro
328A-3G Slaving Accessory

Asking $800
