DigiDash Wiring Question

[Alan Kramer]

I'm working on swapping a digidash for analog gauges (1987.5 CGT) and I've 
run into a wiring quandry...

I have two wires which I cannot identify what they do on the 1987.5 CGT 
35-pin connector at the digidash:

The first is blue with brown stripes running ACROSS the wire, not down the 
length of the wire (I don't know where this goes).   The other is a solid 
green wire that runs between the ECU and digidash.

Bentley says BL/BR = coolant temp.  There is no other BL/BR wire, so is this 
the one?  Why do the stripes run differently?

The other is solid green and comes from the ECU (so Bentley says).  I 
remember on my '83 CGT and '86 4kq there is a green wire running to the 
ignition coil from the ECU...  Is this the tachometer signal?  That might 
make sense because I cannot find the red/yellow wire on the digidash 35 pin 
connector that should be for the tach signal.

Can someone who has experience w/ the digidash please verify that I have 
guessed correctly what these two wires do?  I have all the other wires 
figured out so I just want to be sure...

Thanks!!!!!!!
Alan
