Hello, my name is***** number for resistor is 89018537, I'd recommend buying original resistor so it is a simple plug/play. Here is a link to buy, let me know if you have more questions. Thanks.

I went to the dealer to get the OEM unit. Parts guy was the one that told me I needed to cut the housing due to the redesign. I'm looking for the template used to cut the housing.

I don't have any of this info, I'm not sure if it is in any documents. I'll open question back up to see if someone else has the info, thanks.

Hello and welcome to JustAnswer!

There wouldn't be a template to modify the housing for the replacement blower motor power module, slight design changes often just require slight trimming with a razor or hot knife to allow clearance for it to be inserted. What you'll want to do is take the new one to the heater box and see where it's going to hit and the heater box will interfere with it's installation, and carefully trim material as necessary.
