My 2003 Blazer doesn't have homelink. So I purchased a new overhead center console. The console has the 2 lights, moonroof button and now 3 buttons for Homelink.

3 of the wiring harnesses are interchangeable. The other 2 are not.

Anyone know if it's possible to make the new one work or how to wire it?

 

According to my references, all you need is power, ground, and the dimmer signal which may or may not be up there already. Power and ground should be there.

 

They are not there. When you look at my current connectors there are 3 pins inside. The new one has 5 pins inside. Also where you plug in the compass is small and only about 6 pins across on current one, new one is way wider with 9-10 pins across.
