I own a 86 2M4 and am wondering if there Is there a way to add the aux. guage cluster to a 4 cylinder. I have checked everything I have here with no luck so far. Also is it possiable to use a 120mph speedo in this car. Or are there any mods that need to be done to make either or both work if at all possiable.

The aux. gauges will plug right in to the Fiero.You need the 8" long harness for the gauges,it plugs into a connector towards the drivers side bottom of the center console.
As for mounting you need an aux. gauge console or you will have to cut an opening into the top of your console.The aux. gauges mount to existing screws,just an R+R job.
Should take no more than an hour to install.
The 120 mph cluster is also plug and play except if the new tach is from a v6 and you had a 4cyl.you have to swap the guts from the old tach into th new tach so it talks 4 cyl.instead of v6.

i dont know for sure,but ive heard all 85+ fieros already have the gauge wiring harness in it even if it is a 4banger.ask someone with the gauges where the harness comes out from and see if you already have one

Mines an '86 4cyl. and I hooked it all up with no problems except a 10 minute think session about the tach.Everything works fine on mine...

Thank you all for the help. Im sure this will help. Thanks again

The 86+ have the harness already wired for the ralley gauges... the 84 and 85 do not.

I have the dash out and the center radio console out and cant seem to find the plug for it. Is there a specific place that it usually is at?
thanks

The plug is in the left, lower corner of the radio-heater stack. It is a square eight pin recessed male plug. At first glance it may look as if it is connected to the left side of the radio. LOL!
