I have the stock speedmeter without the tachometer , how I can install one and which one for preference ?

 

you mean an aftermarket tach?

 

well I can change the full board to one original with the tachometer , or simple add a aftermarket tach

 

but I don not know how to do both ones -_-

 

After market is quite simple, but changing the gauge cluster is even simpler. To change the cluster you just need to find a cluster with the compatible year of you're truck, so either 92-93 clusters will work for those years of truck or if you have a 94-96 truck you need to find a cluster from those years.

To install an after market tach you should have about 4 wires, a black ground wire which can be wired to anything metal in the cab, a red power wire which can be either wired to the fuse panel key power or the battery, a white wire that you attach for the light and a green wire which connects to the negative side of the coil under the hood.

 

Option 3 is '87 - '91, should he happen to have an 8th gen truck. I happen to have a spare one of those w/ tach - if interested PM me.

 

I will try to find the right cluster,I just need to change it right ? my question will be the new cluster has the Tachometer how to connect it ? I need another cable ?

 

What year is your truck? If it's 92+ it's all electric and plug / play. I'll post a how to in a bit here

 

It is 96' and thanks for your help !
