Just had a look at old threads and I get the idea that all i need is the one blue wire from the premier wiring loom for the light and a thicker red cable to the starter motor. Is that right?

I have B+, D+ and W marked as three connections on my zetec alternator. Which ones do i use for which wire?

B+ this is the alternater output and would normally have a thick brown wire but maybe red in your case. the D+ normally would have a thin wire this is your field wire and this goes to ignition warning light.The W is not used.Not certain of premier colours

Thanks Very Much!
