Title: installing tach
Post by: maxpoter on December 06, 2013, 01:25:14 pm
ok hope I get this right    I’m working on restoring my 1987 sierra classic .  I have owned this truck since it was new and it is like an ole friend. That being said, I would like to install a tachometer. My truck does not have one and I want to stay as stock as I can. I have seen interment clusters for the same year with tachs.    How much of a task would it be to install one of these clusters in my truck?   Or would it be cheaper and easier to buy a gm tach and fuel gauge and put them in my cluster.  I want to do as much as I can but I do know my limits   I do have some great friends to turn to if I need it        thanks    Max

You would still need the correct cluster housing for the tach since it is cut differently.

If you can not or do not want the gauge cluster you can mount it to the steering column.Just use a large hose clamp and adjust it to where you want it.

Do a search on here (or google- tach site:73-87chevytrucks.com) or check the projects post.  Someone detailed everything about it, but you would need ideally a 81-87 donor with a tach to plug in and make it look right, you only need the printed curcuit and the tach and fuel gage and transfer all of yours over and repin.


BTW, I LOVE my Dakota gauges.  If you go the Dakota route check out our store and create a login and email me what it is for special pricing.

   Thanks for all the suggestions.    I am looking at my options now.  Just to sum it up,   to get the stock look I want I need to get the gauge cluster that will fit a tach.  Then I should be able to get a small fuel gauge and tach and circuit board and install them.  I know I can find someone to hook these up if I have to.  Then use my old gauges for temp, oil pressure and volts.  Putting in a little plug,  I purchased a set of those Whitegauge overlays for my truck and installed blue LED in the dash.  I have to say for the money spent ,that was one of my “biggest bang for the buck” things  I’ve done.  One more thing, I know every case varies.  But what is the general thought of buying electronic parts like these off eBay and such     and by the way::   I asked Santa  about the digital dash:::  she just laughed

Yes otherwise nothing will power the new slot where the fuel gauge went.

You need to make sure you get a cluster that matches the right range of years.  For example, I was able to use a '74 tach cluster from a Suburban in my '75 pickup because they both used an ammeter and mechanical oil pressure gauge.  I could not have used a cluster that had a voltmeter or electrical oil pressure gauge without some significant rewiring.

The basic instrument panel wiring plugs in the same on the tach cluster as it does on the non-tach, but there is a separate 3-wire plug and wiring for the tach (power, ground and feed from HEI).    Its a very simple mod if you get the right cluster.

I LOVE the analog Dakotas.  I probably won't mess with another factory cluster again.  Lots of nice features.
