I'm LS1 swapping my 92 Camaro. Pulling the LS1 out of my C5 and swapping in a 6.0. Years ago I know it was a "fun" project getting the factory gauges to work with an ls swap, but now they're easier if you go with a holley terminator. I'm torn though. I want to keep the factory look and gauges, but I'm also lazy and automotive wiring is/was never my thing. A terminator would be much easier. What are you guys doing as far as the wiring and gauges?

 

There are a couple of routes to take here each with increasing/unique complexity.

• Using the HMI of a standalone system, like you mentioned, that most folks tuck/fit into the middle of their existing cluster.
• Tap into your stock gages, plenty of threads on this and is pretty straight forward, you also keep your stock odometer and mileage reading.
• Stock style cluster assembly replacement such as Dakota Digital and or the Hawks OEM replica unit.
• Full custom cluster with aftermarket gages (tremendous amount of fabrication, "no going back" work, and very expensive). I went this route and you can see what it took me on my build thread. Others have also done the same, with the firebird platform appearing to be slightly less complicated.

Most of the engine related stock gages get their signal from the engine harness. You would treat any aftermarket harness the same way as stock and just tap 3rd gen style sensors into your gages. You may end up with multiple sensors with one being sent to ECM and the other to gage (water temp for example). Spend some time with the search function and see what other folks have done.

 

I didn't know a 91-92 reproduction gauge cluster existed. Even though the price is up there...I think I might just go with a small screen holley setup and get the dakota gauges.

 

Hawks released it not too long ago. I believe its made by Dakota Digital. If you do go full aftermarket do not be swayed by the false advertising that the aftermarket gage panels/chassis are bolt in. They are far from it and require major surgery to your dash.
