Re: [PSUBS-MAILIST] RFC - Standard Thru-Hull Electrical Connector

["Smyth, Alec" <Alec.Smyth@compuware.com>]

Thanks Jon! Responding to the other comments so far... Seems to me the  
Ikelites are something I'd use on outboard cans for lights or cameras,  
but not the pressure hull. Al, I already have the OTS connectors on  
hand thanks to Dan, but thanks for the information. It's curious they  
use a 4 pin, because only two of the pins are connected. What I plan  
to do is solder the OTS cable to the Subconn pigtail and RTV over on  
top. I've had the same arrangement for years on my comms without  
incident.

Thanks,

Alec
