are you talking about adding aftermarket guages or are you talking about switching in a stock guage cluster with the full package?

I doubt you will blow the motor if you have an auto

 

basically if you want to add aftermarket guages you need to do three things pick a guage and buy it, figure out where your gonna put it, then put it in most guages come with some sort of installation instructions. Most tachs only need to hook up 2 or 3 wires (ground, coil, power). The other option is you could get a used guage cluster out of another 3rdgen and slap that in, requires a little bit of work to change sending units and what not, but its pretty easy, and usually looks very clean...although the stock guages arent as accurate as what you can buy aftermarket.

 

I just hooked up gauges on my '86 Camaro. I got a 3 gauge set (Actron off Ebay...hey $20 new & shipped). I put them under the middle A/C vents. I took the vents out, mounted the pod, then put the vents back...also I angled them towards me. They work fine. The tach (Sun from EBay) I put on the steering col. To make your life ez...put your ground near the fuse box, 12v & lite dimmer in the fuse box. You should Only have 3 wires running in your engine area. Tach, Oil, & Water.

 

Supposedly though, the closer you can get the tach's ground to the battery, the less the tach will fluctuate. If you do a search, I've posted a few times on where to connect the tach into our car's wiring harness.

My tach hangs so it blocks the driver's side a/c vent. My mechanical oil pressure (had to remove the bulb from the dashboard so it wouldn't tell me "low oil") and mechanical water temp gauges are on a dual a-pillar pod; tach is Sun 2 5/8" super tach, oil/water is the $20 Summit 2" oil/water package, and gauge pod was from Summit for $20 (back in '96).
