Right here's how my seicento 1.2 16v is wired up. It was a 1998 sei sporting SPI...
This goes in seicento to punto order
Black to Black/Purple
Blue/White to Blue/White
Think Pink to Red/Black
Thick Red to Thick Red
Red/Black to Blue
Purple/Black to Grey/Black
Orange/Black to Orange
Grey/Green to Grey/Green
White/Green to Grey/White
Yellow/Grey to Browny,Yellow/Grey
White/Red to Blue/Black
Green/Black to Brown/White
The I've took the Red/Black for the reverse switch back to the punto Red/Black. This is a slight problem because if you leave in reverse while cars off the light stays on. This worked for me so hopfully will work for you
Cheers
Jef
