Factory tach in 91
Looking at putting a tach in my Suburban, but do not want some gaudy looking thing hanging off the steering column. Looking at available parts at LMC using the factory style parts. Tach next to the speedo, and moving the fuel gauge to the lower left corner. Anybody tried this or have a list of pieces and parts.? The price for parts at the moment is about 350. with what I think will work

Re: Factory tach in 91
Have you considered the tach from gmsportssalvage? I think that's the name. OEM appearance and the fuel gauge is in the 6 o'clock position like it was on the heavy duty trucks of the era.

Re: Factory tach in 91
Similar thing I am looking at in the LMC catalog. Just wondering if anybody has done the same thing and what the results are/ were

Re: Factory tach in 91
If I were going to do it again, I might try the one Timber suggested. I pulled it up and they now have a stand alone tach with fuel gauge in lower left.
http://www.gmsports.com/tags/tachometer When I did it, I didn't want some big thing hanging there either. I found a small one and then did major mods to the cluster to get it to fit properly.

Re: Factory tach in 91
I'd like to put the fuel gauge in that spot just like the factory did and have the tach where the the current fuel gauge is.

Re: Factory tach in 91
I put a factory tach in my '89. It's tight but a tach can fit in the electronic speedo 90-91 gauge case. Im about to do it to my current '91.
Factory tach is a stand alone gauge. Pull the pins for the fuel gauge from the harness, rewire to small gauge and you're golden. |

Re: Factory tach in 91
That's the kind of answer I was looking for. I need to pull apart the dash for other repairs and I wanted to do everything at once including a new stereo. What about opening up the hole in the metal plate for the fuel gauge in the lower corner?

Re: Factory tach in 91
The metal plate is actually plastic. Exacto knife makes short work of it. Use gauge panel as a guide.
You'll need to drill a hole in the case, behind the fuel gauge to run leads from the main harness fuel gauge HOT. The fuel gauge is direct fit. Uses the clock mounts. Run HOT from the main cluster harness to fuel gauge and run a ground. Done. We are just by passing the printed circuit to fuel and just running hard wired to new small gauge. The tach harness passes thru the big fuel gauge you'll be replacing. No cutting or drilling there. GM never change the cluster case. And tach mounts in same spot as fuel gauge did. Lots of mis-info out there about how this isn't even possible with TBI, after '86, with 700r4, or with blah blah...works just fine. Here's a better picture of it. |

Re: Factory tach in 91
Can both tach and fuel gauge be purchased aftermarket?

Re: Factory tach in 91
I got them both from LMC along with the tach wiring harness and tach mount. Had to change the power lead connector in the tach harness so it would plug into my fuse block. I also had to create my own small harness for the moving of the fuel gauge. Pulled the wires out of the dash harness and extended them to go directly to the gauge bypassing the printed circuit

Re: Factory tach in 91
Wasn't too bad. Cutting out the shell was a little tedious without damaging it as they are no longer available new. But yeah, I think it came out ok.
