[R-390] Wire harness

[Roger Ruszkowski]

Robert,
 
The plug is P114 it goes to jack J114.
 
>From the photo, it looks like there should be enough wire in the plug to allow you to identify 
each wire by color and stripe. You can find its mate in the cable section.
 
Work the cable back and write down the wire colors and stripe set.
Do a wire splice and shrink wrap tube on each wire.
Leave the splice set nice and long.
Get a nice length of coax shield braid and squish it back big enough to make a sleeve
over the harness splice and extensions.
Work if back on the harness far enough so you still see the wire cover color and strip.
 
Trim all the wires to the same length and strip them to 1/8 inch.
 
Open up the plug back shell and slip it onto the spliced cable.
Take lots of pictures of the stub wires in the plug.
 
Unsolder one wire from the connector find its mate in the harness by color and strip.
Solder that wire back in.
 
repeat for each wire in the plug.
 
Dress the coax shield down to look nice and trim.
 
No TM NO Schematic NO problem.
 
Reinstall the plug back shell.
 
There are 4 plug and jacks in the R390 that are the same part pair set.
 
J214 P114
A 180 Volt B+ also on 180 volt test jack for test check switched B+
B Filament string  25.2 Volts  also on P113C for test check

At least one pin is ground. I did not see the other pins on the schematic.
I did not find a wire list for the plug and jack in the TM

watch for a direct mail with TM PDF file attached.
