Look at this manual and see if it matches your color head.
If so the wiring instruction is on page 6 and 7.
Note that there is a very important caution in the instructions.
Thanks for the link, my colour head is the Dichro 23dga. I will look for manual but it seems there is not much on this head. I also got the condenser type light dome and glass, I wonder if I should change it back to just that for black and white work,

Thanks and if you have a link on the 23dga I would really appreciate it.
Thanks again for your help
Yes I stumbled on the other link.
Some instruction manuals are VERY hard to find for free and you may just have to buy it.
You can go to Ilford site and I think they have a table of the color head setting to equate to MC filters.
Then you just dial in the setting you need and go.
But there is nothing wrong with a condenser enlarger.
Just buy a set of Ilford MC filters of the correct size for the enlarger.
It really isn't much of a hassle to use.
And this will also let you start to use your enlarger while you are figuring out the color head.
BTW do you have a manual for the enlarger? If you don't that same site has manuals for the 23C.
Pay attention to the setup process for using the condensers. You have to adjust the condenser height based on which lens you use.
Thank you so much for your help.
