Today decided on how I was going to handle the ground buss, I'll post some pictures tomorrow. I then installed a noise filter for the avionics buss and wired the engine instruments, installed the EGT gauge which finally turned up. I'm not crazy about how it looks compared to the VDO gauges but it will do. Also wired the Turn and Bank indicator, engine ignition switches and installed and wired a proper Constant Contact Solenoid. I managed to pick this up from the local auto electrician, its a 100 amp solenoild with silver contacts, $30.00.
