I recently purchased a new cluster for my '03 Suburban 1500 (4WD) and installed it today. I upgraded from stock to include the trans temp guage, which I din't have before. I noticed that it didn't appear to move at all after the install and was wondering a couple of things. Supposedly the vehicle is pre-wired and it should basically be plug-and-play is what I was told. So it it true that my vehicle should already have the temp sender? Also, I only drove it about 5 miles, but shifting through all the gears, I figured the guage shoud at least move a little bit.

Anyway, just looking for some input.

Thanks Guys.

 

it should have one, try driving it a little longer and see if it moves. i didnt think the 03 clusters had to be reprogramed.. so give that a shot if not let me know
