Thank you buddy craig for the informational diagnostic videos you posted a while back. I determined that the isolation relay was more than likely my issue. After calling several parts stores and not being able to find this specific relay I turned to the forum. I now understand nobody really makes it anymore but the fiero store has a few OEM ones they are selling off? As it turns out... Im very cheap. I have a feeling there are many individuals here that can relate to that. SO what the hell! In the spirit of Halloween lets cut this up like a katana to a Zeds torso. Props to you if you even know what that is.
Two min with the dremel resulted in this carnage.
At this point I completely understood why why headlights were not functioning properly. At first i was thinking maybe i could turn it upside down in some muratic acid and see what happens. I decided not to. I dont know how the plastic will react and its so far gone that the wires would probably fall apart. So that led me to a few more min with the dremel and i got this.
Now im feeling like i have something to work with. I cleaned it up and soldered some wires to the leads and got this.
So now with whatever i decide to do with those wires, ill be able to leave the stock connectors unmolested.
Of course Ill be adding a few universal MUCH CHEAPER relays to those wires. I did see on a miata forum some guy had a few switches to control each headlight motor individually, and could make them "wink" and give the car "sleepy eyes". I thought that was kind of neat.
Basically one relay for up, and one for down. Anyone with basic electrical knowledge, and a cheap soldering iron can figure this out. Id imagine if someone took the time to make the wires all the same length it would look better as well Oh well. Thats what electrical tape is for right?
..whatever haha A for effort.
It does work exactly how I need it to. The Fiero harness energizes the relays via control of the headlight switch, the relay connects an added fusible power wire from wherever you want to connect it. I utilized the ground in the fiero harness PLUS I added a chassis ground for fun. I think the best part of this little project is that it was all made from junk i had laying around the garage. I think I had those relays sitting around from a ford Taurus I put together about 6 years ago. I knew those relays would come in handy someday.
And that's why people replace the 84-86 headlight system with the 87-88 system.
The gen 2 is certainly a far simpler and more reliable system, but the actuator modules that control the headlight action do occasionally burn out. The good news is that the 04 Corvette used the same module so they are still available. As for the headlight actuator relay on the 84-86; a DPDT relay was used and this relay type is widely available, low cost but not as a direct plug in unit. Forum member Bloosberry posted the diagram several years back for wiring in a new DPDT relay and it should be in the archives.

I did that once before, but for some reason I think I only used one relay.
I did something like it also in a 82 Trans Am. I used a 4 pole double throw relay though, but I can't recall if it was 1 or 2 of them (I think it was only 1). The motors are the same as the 84-86 Fiero if memory serves. I don't remember why I didn't just go to a junkyard and try to get a couple of relays there to try out but I didn't. It was really kind of nice after that though as the previous owner had just left the lights up and unplugged the motors. One of my big gripes with pop up headlights...

Lol I was waiting for that fireboss. Thank you I can see how one could get away with just a single relay...or no relay, but come on... Would pinball machines be that much fun with onlyyyyy one relay? I rest my case.
Chris Hodson's two relay approach will certainly work fine but what I was suggesting was a DPDT relay. In other words two SPDT relays in a single packaged unit. I don't want to start drawing the wiring out as Bloozberry has already done that. I will see if I can find his thread.
