Noob here,

In an effort to comply with local laws calling for white parking/running lights, I have installed switchback LEDs up front. The turn signal flasher has been updated and everything appears to be working. Switching out the hazard flasher is a different matter, though. First of all, it is very difficult to access. I have removed the horn relay and the metal "v" bracket under the steering column to give me more clearance, but even so I find myself sweating and cursing in a futile attempt to seat the new LED flasher.


Convenience center... more like in-convenience center, am I right?!

First question: Is there a way to provide even more access space to the convenience center without tearing everything apart? It has been suggested elsewhere that the center is somehow hinged and could swing but I see no evidence of that on a 1990 IROC.

In the case of both the turn signal and hazard flashers I am using a wiring harness that gives me the opportunity to change the polarity of the connection. Without it the turn signal would not blink at all, just light up as solid amber. During my struggles, trying to plug in the harness for the hazard flasher, it suddenly just slid into position with one pin oriented up top and the other toward the driver's seat. Exhilarated I connected the flasher to the other end of the harness and turned on the hazards. Everything appeared normal on the dashboard but walking around the car revealed that only the rear and one front indicator came on. The side markers and front passenger indicator were all out. Changing the polarity only resulted in no lights at all. I tried an alternative LED flasher with the same result.

Second question: Did I position the harness incorrectly? Well, I must have, mustn't I? I can't determine whether there are one or two ways to orient the flasher connector in the convenience center. There must be two, right? The way I've managed to do it and then, possibly, one pin up top and the other pointing toward the engine? This is SO frustrating. I don't know how much time I've spent on this thus far.

Any advice from someone who got this to work would be appreciated. Thank you.

 

Update on my second question: I have concluded that my hazard flasher was seated correctly the first time (one prong up top, another pointing toward the driver's seat). Moreover, one of my switchback LEDs had come loose. It lit up white but didn't flash amber so my original statement about the turn signals working was not right. They do now, though. Strangely, the side markers only blink if my parking lights are on. This is not really a problem because I'm required to use daytime running lights but I would like to understand why blinking is determined by whether my parking lights are on or not.

On a semi-related topic, I've missed the turn signal clicking sound ever since upgrading to a LED flasher. Fortunately LED flashers with sound are available. I bought a pair off memotronics.com, just a heads up to anyone who might be on the fence about upgrading due to the lack of sound.

 

That was one reason I WENT to an electronic flasher, I was tired of hearing the sound, it's redundant and unnecessary since I have eyes and indicators on the dash

I read your original post last week, but I don't really know what you're looking to have answered. If you need more space, remove the hush panel, I honestly don't know how you got the other panel off with that still in place. If you need more space, remove the drivers seat so you can lay flat on the floor.
As to the second question I can say is that the electronic flasher I bought was polarity specific, so it didn't work in my one vehicle. I had to pull the terminals out of the fuse block, switch them and then re-insert before the flasher would work. You can get a 3 wire, but that may also be polarity specific. You also haven't given any details on the specifics of your car, but I don't remember a flasher by the convenience center in any of the cars I have worked on. The flasher was in the fuse block(?) and the hazard flasher was separate just floating in the dash hear the fuse panel, clipped to something. I don't even see a flasher in your picture.
