cooling fan relay switch

[davevette]

Hi,
I am trying to hook up a manual switch to the primary and secondary relays for the cooling fans. I have a 1994 Coupe and need to know which wires to connect the two manual switch wires to. The instructions say to connect to cavity number 86 on each relay, however, my relays are only indentified by by letters
E D C A and F.
The instructions also indicate connecting to the dark green/white wire on the primary and the dark blue wire on the secondary. My wires are not these colors. If anyone can help, or point me in the right direction, I will be very grateful. Thanks, David

Fan switches working great!! Thanks for the help and for the welcome. Actually, I've been here for about six months but I changed my e-mail and it was easier to just re-register. Also, I now have an automatic fan switch package that I bought from Ecker's....if anyone want it, e-mail address and it's yours for free. Again, thanks for the help. David
