installing cruise on an 87+ fiero is a bit diferant from erlier years in that the cruise function is built into the ECM. At least this is true on the 4 cyl. I think the V6 may have done something similar, but I can't confirm it yet.
That I can tell..... Cruise was not available as a dealer installable option. What that usually means is that the wiring harness may not have the extra lines in it. (For example the Power trunk latch is fully wired in all 85+ Fiero. all you need do is drop in the rest of the parts.)
That being said. at the very least you need to tear apart the column to install the corect turn signal stalk. then install the wiring. then install the control pod and throttle linkage. You also have to install the brake/clutch switches.
How much worse this is depends on if the none cruise cars have the plugs in the harness or not. I really don't know..... I've thought of doing this, but haven't had time or access to an 87+ that I can strip parts from. Judging by the earlier ones I've looked at a bit.... It's not going to be easy.
I can tell you for pretty sure that you can't use some or maybe all of the parts from a pre 87 car..... Pre87 uses a seperate module for cruise. Like I said above... 87+ cars have it built into the ECM..... Add in the alteration to the throttle linkages required by the 700 TBI....... (the 300 unit used thru 86 is completely diferant) How much change there is in the V6 and it's electricals I don't know, but on a 4 there are plenty.
