[TR] TR4A overdrive column switch wire routing?

[trguy75 at gmail.com]

Anthony:
Having just restored my 4A steering column, I am very familiar with the process. It is not a quick job to do it right and not ruin parts.

1. Undo bolt on the wire cover that surrounds the steering column.  You are going to have to remover the cover towards firewall.
2. Undo the bolts to loosen or remover lower steering column locking bracket attached right behind the dash.  Two pieces that are silver. 
3. Loosen the support stays attached to that bracket. 
4.  This should loosen the steering column and provide some "play" so you can get the wire cover through the dash.
5.  Be careful loosening the wire cover end that goes around the steering cover under the dash.  You will have to gently pry the two ends apart to loosen it around the steering column.  
6. with play available route the OD switch harness through steering column, out underneath the column and through the dash with the other wires.
7. Then put the wire cover back on and slide through the dash opening into the steeing column opening where the wires all come out. 
It takes a little time but thatr's it.

Subject: [TR] TR4A overdrive column switch wire routing?

I am looking for advice, even photos, of how to route the wires from an overdrive switch (mounts to the left hand escutcheon) on my left hand drive TR4A

I am going to be adding an overdrive to my transmission this fall, and I am trying to get the “easy stuff” done ahead of time.  

As I look at the column with the original escutcheon halves removed, I do not see a good way to get the wires into the column “head” to join the other switch wires.   There does not seem to be much room to feed them in without pinching against the metal of the column, but if it goes forward of the turn signal switch.   And if the wires pass rearward of that switch then they could interfere with the self-cancelling mechanism.

And then once the wires are in there, how do they get fed down and out the column to go into that long narrow cover on the bottom of the column along with the other wires

And those wires already there seem to completely FILL the available space inside that cover!

How do I free up that cover to get
It loose enough to pass the OD wires?

So many questions!!!  Sorry!!
