124 blower motor regulator assembly

I just diagnosed mine as bad when I got the proper voltages at the regulator but not at the 3 pin firewall connector.

Does the new assembly come with the 3 wire plate connector or just the big aluminum heatsink? If it's just the aluminum heatsink, I was wondering what can go wrong with this thing? Since they're so expensive I was hoping I could clean it up to maybe solve any heat dissipation problems it may be having.

Anyone know how these things "fry"?
