Had steps installed today. I'd decided against adding steps or boards but my wife needed a little help. Oh, and anyone who claims there's a finger blocking part of the picture is lying.

Which control unit did you get? I saw new Delco and Dorman ones are being made.

Suirrrelsmith,

How did you glue the hooks? I have weathertechs too and tried to thread the hooks into the carpet but it didn't stay put long. Thanks.

Have a link to the Hayden controller? What temps did you set them on? Working good?

I believe it was a Hayden 3647. Works perfect. I have it set around 195 and when they do kick on, you can watch the temp gauge almost instantly drop. It was not a direct drop in, I cut out a good portion of the exterior of the shroud to make it fit and even then, it's such a tight fit, it barely moves.
