I've got my (previously discussed) annunicator panel figured out. 

Now I'm trying to determine the best way to connect all the 

different sensors, switches and devices back to the panel. So far, 

I've come up with a few options:



1) Hardwire everything to the annunicator panel.

2) A single DB-25 which is then split out to all the different destinations.

3) A Molex connectors for each destination.

4) Inline PIDG connectors for each wire.

5) Hardmounted terminals (spade or screw) on the annunicator with 

PIDG connectors for each wire.



Any opinions on which one would be best? Or suggestions for an alternative?


	


   You're discovering that a small fraction of the

   effort is to make it work, the largest fraction

   is package and install it.



   In my personal experience . . . anything you can do

   through a d-sub connector with machined pins

   is of good value. For bringing flying leads together,

   the PIDG knife-splice under heat-shrink is an

   efficient, cost effective joining compatible with

   common tools. Molex connectors are at the bottom

   of the barrel for choices . . . bulky and they

   use b-crimps which are not 'bad' but not the

   best we know how to do.

Machined pins by themselves, without a DB 

housing, make handy, very small, removable butt 

connectors. Â A piece of tight heat shrink will 

hold the whole thing together. Â Good or bad, the 

entire connection disappears in a wire bundle, it's so slim.



    Yes! I've illustrated the technique at:

Also, I recently did an install that needed power 

to 5 or 6 engine sensors. Â The sensors are all 

very low current and fed from a single wire out 

of the engine monitor, so I used Bob's DB ground 

block philosophy in reverse: Â I soldered the 

wire from the engine monitor to the back 

terminals of the DB sockets, then distributed 

that power to the various sensors through the 

other half of the DB connector. Â I used the 

plastic body of the connector to insulate the whole thing.



    The d-sub can be pretty versatile.

    The technique Dave is talking about here

    is illustrated at:

Bob

What do you recommend for removable connections for larger single wires, say

16 or 14 gauge? 

Would a "B" crimp male and female with heat shrink be ok?
