Toast,
There are a number of connectors that work in this application. All of them available from Digikey (First sponsor in Minnesota). If you have good soldering skills and can handle the cost, Switchcraft makes a mini version of their XLR connector line. These connectors latch together so they won't pull apart in high G collisions and are available in 4 pin version. My personal recommendation is to select a connector solution that can easily be pulled apart and then allow the offending device to be isolated by connecting to the remainder of the string.
