Looks like you bought the same one as me...I'm about to fit today. Have you already done yours? The info I have so far is...
1. Red & black easy: +12V permanent and earth
2. At the bottom of the fuse box is a 40pin connector. In this, you will find: White and green wire, this is your LOCK wire. Goes to WHITE on remote Blue and purple wire, this is your UNLOCK wire. Goes to WHITE/BLACK
3. Punto has NEGATIVE trigger locking, so YELLOW and YELLOW/BLACK to on remote should be GROUNDED (with black) on remote
4. To get indicators to flash, pink & pink/white wires are the ones you want.
how do you get on cos i'm fitting 1 to my multipla, the wires are different colours but following the multiplas wiring drawing indicates its the same set up as the punto.
