Re: EV630 Wiring



Luca, thanks very much for the response. This is tremendously helpful.
I've had one other reply, off-list, so I'm gonna put the 2 together,
compare notes, and "plug-n-hope". These have given me quite a bit to go

your collective infinite wisdom), pullease, don't be shy.  --  Phil Neal
