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.

god damn. you really have to want to do this.
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?

Not sure but thought B10 was for running MAP ?

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.

Yes, that pic explains it well. Thank 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?
