Sounds good. One less problem to worry about.  ;-)

I've never done this conversion before. In fact, I've never actually 
seen a '68-9 with the Cold Start Valve option. So I'm not completely 
sure what the right thing to do is. I agree that removing the CSV is 
the best thing to do.

Here's what I can tell you for sure: Both options used the same exact 
brains, A or B. The B version is the better choice. On the option 
without the CSV, wires 14 & 9, coming from terminals 14 & 9 on the 
pressure switch, go to terminals 14 & 9 on the brain connector.   

It's possible that terminal 14 on the brain is a ground. If you 
verify that with an Ohmmeter, then grounding wire 34 (which replaces 
wire 14 on the CSV option) would be equivalent to running a wire back 
to terminal 14 on the brain.

Terminal 11 on the brain is a ground, so if there is little or no 
resistance between terminals 11 & 14 on the brain, then terminal 14 
is a ground on the brain.
