I just ordered a power window kit from A1. The same bolt in power window kit offered from most mustang suppliers. I am excited and a little nervous about the wiring. I ordered a wiring kit from Spal that will go in my center console. How easy are these kits to wire? If the windows are currently stiff to roll up will I need to do something other than grease the tracks?

 

You may have to pull the tracks out and give them a good cleaning before relubing them. The lube has a tendency to collect dust and harden over time. Also replace any rollers while at it.
