Jeff,

The connector originally used on the 4P firewall is an Amp=20 (Tyco) 206127-1. According to the Amp spec = sheet it's=20 rated to 30PSI. This is a bulkhead connector with male pins on = both=20 sides. On one side of the firewall use an Amp 206125-1 = mating plug=20 and on the other side use an Amp 206126-1 plug. Use Amp 205090-1 = sockets=20 to populate the plugs. All of these parts are available from = Aerocraft=20 Parts (Lancair). On the website they're listed under "Amp = Connectors", not=20 "Firewall Forward Connectors & Tooling". Apparently some = people=20 are opting for the more expensive connectors listed in "Firewall = Forward", even=20 on non-pressurized planes, because they are more fire resistant than the = Amp=20 connectors.

The Amp connector set provides 28 contacts through the = firewall and=20 you mentioned you need 31 so you'd have to use two of the Amp = connectors. =20 I think the connector listed under Firewall Forward is an RMS = connector. I=20 don't remember how many contacts are in it but RMS does make a variety = of mil=20 spec connectors and they do have a 31-pin configuration. Check out = ht= tp://www.pan-pac.com/products/viewCompany.php?company=3Drms. =20 Google also pointed me to www.introcorp.com/rms.html= but I=20 couldn't access this website. Maybe they're down over the Easter=20 weekend.
