do you mean 4 on the new one ???

[neilrmp]

oh sorry I have the pics reversed, so the wiring will be different, do u have a pic of the bulbs connection?

[neilrmp]

yes it is #4 on the new one not used, you will be using six (6) wires and #2 and #7 will be together on the bulb side. the numbers # are for the old one, sorry.

I'm not an electrician but i stayed in a Holiday inn last night

[billy2]

thanks guys can i ask is the pic that jebo put up is this the right why of doing it ????

[hugh jarse]

follow the wiring diagram on the ballast and use a connecter block to join the wire that links the lamps
cant tell what the numbers are from the pic but as you look at it they are the top and bottom wires(joint these)
