70 cuda dash lights

noticed I had no dash lights Friday night. First time out at night with car. On the back of the dash light switch are three terminals. Could someone please explain what wire goes where such as the power in, out to lights and what the third terminal is for.

See my switch faq here for more info on the dimmer switch function. This also shows you how to test the dimmer switch:

I have the same problem but mine keeps burning the fuses. Is this a common problem or I have to inspect all the wires in order to find a short?

I was reading your test page and had a question.
I was rebuilding a dash for a customer, (71 Cuda) and was trying to connect a 3 speed wiper switch to the harness. It wasnt right for the harness connection.
I contacted Jules the Wiperman and he told me that 70 and 71 used either a 2 speed or a variable switch. The 3 speed switch was a 72-74 item. Whats your take on this?
I see you talk about testing a 70-71 3 speed wiper switch. Just want to get my facts straight for future reference.
Thanks.

Jeff,

All of the 70-71 rally gauge cars I've done had the 2 speed variable. The switch you're looking for will have a red dot on the back with the number 25 on it (easiest way to identify).

There is an extra spade on the back of the switch, if you look, you'll see which one isn't used, it has a barb sticking out so you know which one never had a plug on it.
