cluster with built in tach

i have a guy at work selling a cluster out of a 91 b2200 and it has a tach built in. I need to know if the cluster just bolts right in or do i need to do any extra work to get it to work.

bolts right in clock wont work unless you wire it up yo umay need to move your speedo cable over a hole

I think that only apply's to the b2000 models I think they just had one wire harness in the b2200 that had the wire there. I have read lots of times were peeps with the 90 model trucks just plugged them in and everything worked. But even if it does not its pretty easy to do and you will have to move the speedo cable to the left. if not it will bind and break it.

i did this in my 92 and clock works with just plugging it in but i heard people say u need to add the wire but i tried mine and didn't have to add anywires and ya i moved the cable over a hole

i put one in my 88 and the clock didnt work. fyi
but come to find out the entire thing didnt work lol although the gas/temp/rpm did work lmao

must be the 90's models i put the tach cluster in my 88 and clock didnt work and its a b2200

Maybe

This shows how to switch from non-tach to tach cluster. And have the clock work
