Gauge cluster swap

[Zoofly]

Without posting pictures, I'll try to describe what I'm wanting to do. I had a custom instrument cluster made and installed at Allison's. Mark added an Oil Pressure Gauge which my '78 didn't have. That new gauge has a different design than my Gas and Temp gauges. The Oil gauge has yellow writing and also Italian description of the gauge, "Olio". The needle pivots from the top of the gauge, compared to my Gas and Temp gauge with the needle pivoting from the bottom. I'd like to have my Gas and Temp gauge in the same design. I was able to find the Gas and Temp gauges on eBay that match my Oil gauge. My question: Is it a simple swap? No re-wiring of the pigtails, just plug in the replacements? Or am I looking at a bigger project?

they work fine, Benzina and aqua, together with Olio. only thing is to make sure the position of the pins in the plug is correct for your wiring. Given the changes that often happen to old cars i would get the wiring diagram from Mira and then check that the new ones match up. when they do, plug in and play. I have done both my fiats exactly like that.
