well it gave the desoldering station a good workout :) works well.
i'm a little of the way through it. printed out an a3 page so i am not scrolling through the bloody computer every 1 second.

note ; if you are going to use in a later model (like vx) get the ECU plugs from a vt berlina or calais ... as they have things like the PRND321 indicators :)


So I’ve just made my conversation loom wondering why I’m missing the PRND321 wires on my harness... guess this is why!

In addition to the grey wire being left I’m left with 2 other wires:
B10 (light green)
E9 (pink)

Will I have any issues with those 2 wires being left out?

Correct B10 is Map input but only for a Kalmaker bin. On the factory VT B10 is for EGR

E9 is one of the wires in the 4 pin PRND321 plug

A question regarding the spreadsheet for Flash to S/C PCM conversion. For example with Flash PCM pin A1 to S/C PCM does that mean the wire is doubled up for pin C13 and C14?
Thanks

This might explain it a bit better for you.

yep the 2 lines are multiple on other pcm and single on the other which are the same thing.

Would it be easier to re-pin for the '396 PCM or make up the patch harness?
