I'm installing the LightSpeed Plasma II+ ignition in my RV-9.  

The wiring loom from LSE comes pre-fabricated from the crank 

sensor in the flywheel all the way to the DB25 that connects to 

the ignition module.



I want to put a disconnect in the crank sensor cable forward of 

the firewall so that if I ever have to remove the engine, I 

don't have to rip up the wiring inside the panel aft of the 

firewall which, is where the ignition module will be housed.



Can anyone suggest a good quality in line connector that can 

serve ?  It needs to have six wires, 2 of which are for the 

separate shields on the two separate channels.



I guess the requirement is that the connector should be capable 

of resisting the typical heat within the cowling, cable of 

mechanically isolating "pin" connections from any vibration in 

the cable sheathing, have good shielding capabilities (since 

its a sensor cable).



Thanks in advance ...

 Gerry,

  

 The DE-9 (usually called DB-9) is a good choice.  Some do come0 with Teflon insulation, but I can't give you a part number.  Those0 should be good for under cowl temperatures.  If any of the wires carry0 significant average current, I would parallel 2 or more pins.  Whatever is0 done in the DB-25 should work going thru the firewall too.  FWIW I have0 used these connectors for 70 amps peak on a single pin in CD ignition systems0 with no problems.  This was a prototype of an Indy car system.
