Glow Plug Control Module

OK, what does a glow plug control module do? The short bus I got has one on it. It looks like it fits right into the circuit without much, if any, modification. I got one with my short bus and am curious if it would be something worth adding to my pickup. So...what does it do and could I/should I install it?

Thanks,
Mark

I believe it was only on California trucks and all excursions. Only benefit I know of is it will give cylinder specific glow plug codes. I wish my truck didn't have a GPCM. The simplicity of a relay is better IMO.

Correct. It's on the CA trucks. It's used instead of a glow plug relay (and more expensive).

A more expensive and complicated way to do pretty much the same as the GPR, I wouldn't worry about moving it over, you aren't really going to get any benefit by doing so. Sometimes keeping it simpler (and cheaper!) is better!
