Fuel gauge to tachometer, clock to fuel gauge

[84_c10_GMC]

hello,

Has anyone used the summit retro gauges to replace their square body gauges? I am looking at replacing my large fuel gauge with the tachometer and the small clock with a small fuel gauge. They appear to mount the same on both, just curious how they look after installed. Will be going in a 84 high sierra c10


Thanks

Alex

Hey Alex, when I did that conversion I used the LMC tach kit.

I could be wrong, and I don’t know if Summit includes any provisions for just swapping in a tachometer, but I think it generally requires a new printed circuit, and also the green plastic backing plate that has a space for the tachometer plug to sneak through the back to actually get to the tachometer. Apologies for the poor photo, but the LMC kit is pretty seamless and includes everything you need. Although, it will come with the stock tachometer that goes to 5k RPM.

Thanks for the info. I was gonna go the route of pinning on the main gauge panel plug to get the wires to the new fuel gauge. And then run new wires for the tach. I found someone else post doing similar after I posted this. They used oem gauges off another truck. Although it appeared they didn’t have the clock like mine does. And just had to cut out the blank spot to fit the fuel gauge.

In a different approach, anyone aware of a small matching tach that goes in an empty small gauge location I have?

I haven’t seen any small oem style. But I believe Holley/brothers had some that will fit in the oem guage holes.

The summit tach is 3 wires off back of the guage. Ground power and signal wire. Other post on here used an inline fuse that plugged into your guage fuse panel and kept the original fuse also. And used the wire off the 2nd fuse to power the tach. Signal wire obviously goes to the distributor. So should not be to hard to get tach going. Main thing will be the wiring for the fuel guage from oem location to the clock location.

You’re likely onto something there- I’m a little rusty since I did mine probably a couple years ago.

Whenever I get around to doing it I will report back….. need to get the truck running and moving on its own at this point lol
