Hi, I have an 04 Lb7 and my ending unit went out a few years ago. I recently tried to replace it using the dorman part that I read about on the forum but we broke it in the process. I went ahead and ordered one from TSE truck stuff out of Arkansas gm part dlpfg0358. I received this part today and it has a 4 flat plug instead of the smaller black plug on the original. Will this part work if I change out the plugs? Thanks
