World's slowest Fiero/Quad 4 Swap (Page 48/50)
Quadfather APR 01, 01:46 PM
Spent a couple of hours yesterday working on the harness and finally got all but one of the GTZ plugs identified and labeled and went over the wires I've already attached to the C500 and the C203.





These are the GTZ relays.



The last GTZ plug to figure out is this one.



Seems as though it serves a similar function to the small plug that accompanies the Fiero's C203.



I mistakenly had this wire going to the C203



These schematics from Autozone have been very helpful, I just have to figure out how to actually attach the wires that need a "hot at all times" source. Maybe to the stud on the C500 block?

Zero progress to report. Been too busy with work, problems with major appliances and other issues. I have been accumulating more tools and supplies, and trying to rid the car of mice.



It's immensely frustrating to be at this point in the project and not be able to make progress, but I'll keep working on it.

Zero progress on the wiring harness, other than buying some more tools. Just too busy. While passing through the shop I took a look at a couple of long-term problems: the sun roof gasket and the windshield trim. It's been a few years since I installed the new sunroof seal and I hoped by now the weight of the glass would've compressed it more.





Also having trouble with the new windshield trim. When I installed the sunroof panel I didn't think to check the clearance between the glass and the A pillar. In some areas there's enough room for the trim to fit, but in others it's pretty tight. Don't know what to do about this.







The car could really use a new windshield, so maybe I'll see what a professional can do with this.

I'm scheduled to have major surgery on Monday so there will be absolutely zero progress for a couple months.

If the tight gap is just excess windshield sealant, you can run a razor blade down the glass and remove the excess. That might get you the needed clearance.

Looking at pictures of your Quad-4, I realize how similar, if not almost identical that engine is to the LD9 TwinCam that was in all the GrandAms, Aleros, and Cavalier/Sunfires. I think the LD9 was just the newer version of the Quad-4... supposedly a hair more reliable, slightly less powerful, and supposed to be smoother with the counter-balance shafts.

Yup. The LD9 was an updated version of the Quad 4.

Here's a little video of an unwelcome visitor in the shop.

Oh hell no. I found one of those in my house in San Antonio in the early days when I had first started renovating it. I never want to see anything like that in my house ever again.

Just learned that Sardonyx247 passed away. I don't know that I would have attempted my Quad swap without his thread on his own Q4 swap. His thread was full of great information and more importantly lots of photos. RIP, sir.

I had coronary bypass surgery on August 5th (the same kind of surgery my dad had twice). I'm feeling good but still am not allowed to use my arms for more than just simple things.

For the first time since the surgery I got over to the shop this morning. I've been thinking a lot about the project over the last couple of weeks, including how I'll handle the battery cables. I got a pile of cables and switches from work several months ago and I think I'll use some of them.





I may switch out my homemade metal battery box for a fiberglass one, too. I have one more week off work so I hope to spend some time on the wiring harness next week. Really want to get this car on the road, especially now that the weather has cooled off.

It's good to see your still knocking this out.
I have a lot of end use experience with those battery switches/breakers, I really like them.
