hey fellas, so I have a 99 nbs silvy, I swapped in a 01cluster for the temp gauge and it doesn't read..I heard that the only issue with 99 was if the cluster wasn't from a 99 the bag light would stay on.I know the cluster is good cause i saw it reading temp before i pulled it. do 99 come wired for the gauge?

I was hoping it would have fixed my gas gauge issue but didn't looks like my sending unit is the culprit of the speratic readings

any input would be helpful

truck its in is 99 2wd rcsb 5.3 4l60e
came out of 01 4wd 2500hd 6.0

 

I don't think it did come wire

 

Your fuel gauge reading issue is related to the sending unit. You need to replace the fuel pump assembly which includes the new sending unit.

I am not sure on the temp gauge. You might want to speak with a cluster shop to see what it would take to make it work. It may need some software in the cluster or on the ECU side to make it work correctly. Being the first year of production, it may not be possible. With an advanced diagnostic Scan tool you could see if has trans temp capability's. You will be able to see if it has temp reading under the transmission parameters.

 

i have a escalade cluster in my ex-99 nbs ( sold ) and my 00 z71 ( totaled ) and now in my 01 race truck and one sitting on the bench my race truck just lost mph reading though

it should work!

 

hmmm..well ill have to drive it more and see..I have a big old cooler for it up front and didn't drive it very far at all today..maybe 2miles at 35mph at 30* degrees..I would have bet it was wired up for a tranny gauge.

and ya I now know it has to be the sending unit itself, kinda sucks..I've seen gm sells a gas additive to try and correct this problem. .its around $60 though which is crazy but

seems odd to me that the unit is already crapping out..I've owbed

 

From what ive read it won't work your truck isnt wired for one

 

Did they wire 00 and newer so the swap would work?

 

****..see I read sooo many different things. .I see that 99-07 are all prewired..I know the 99 is the basturd child of gauges haha but thought the gauge would work but the airbag light would stay on .. this sucks since I spent the money

 

so...my bad the gauge does work just takes a bit to warm up in 30 degree weather lol

so if anyone wants to know an 01 hd cluster does work in a 99 nbs

 

Swell didnt know that. Now i wonder if it will work in a 02 with a 80e
