One picture, if I did more I'd be smashing my
fücking phone just having the reminder of what idiots, would go to the trouble of properly wiring up a coolant and oil pressure sensor, but everything else is taped wires.

This would be the 2nd vehicle so far, I have owned which was done so poorly it's beyond ridiculous ffs.

I have replaced the wiring and alternator but not the fusible links.

So....is it safe to use an in line fuse holder? I have never seen the point, of using the links especially when I plan to upgrade the wiring gauges to the fusebox.

I never understood, why GM thought putting two small wires and expected them to handle 60-70 amps plus of current lmfao, it's actually pathetic lol.

There is a sound theory behind using fusible links. They are a slow burn fuse and not susceptible to a short voltage spike the way a modern fuse is. But……..they suck to replace and diagnose what caused them to burn up. On the plus side - they are durable.

Looks like a mix of duct tape and that metalized tape that they actually use on ducts.

I'd laugh, but I've probably done more than my share of 'temporary' fixes that become semi-permanent. Difference is, most of my junk goes from me tot he junkyard. I don't usually inflict my own shoddy work on others.

Whenever I’ve tried that it usually turns out that the ‘others’ you’re referencing is myself haha.

I replaced the fusible links on both of my cars.
I found the wire at an old time auto parts. Delco. I used butt connectors with the shrink ends. Then I covered them with marine shrink tubing. I actually changed the finished one in the picture after I had it done. I started to use 10AWG for the one side (the blue link wire) and switched back to 12AWG since it goes into the bulkhead connector. The other side at the bulkhead is also 12AWG. Didnt make much sense going from 10 to 12.

I also eventually changed the blue wire to purple to match the original. The tube helps keep the wires in place. Nice to have if you can find one.

Yup same I was thinking.

I try to use the factory aluminized canvas heat shielding stuff if I can. This is what I did to my Z06 when I installed the Headers, wrapped some wiring and the Hydraulic Clutch Lines.

Fusible links are slow to blow as stated before designed to withstand an overcurrent for a longer period of time unlike a fuse's immediate interruption. In all my years of being a backyard automotive expert?????? I've never seen a link blow except for melted ones touching the hot exhaust pipes! Also unless it has completely melted it is very hard to physically see it is blown unlike a fuse.

Wow. Speechless. This might be the worst old GM car wiring, that has been posted here.

This is disturbing. As now I am starting to wonder if this vehicle had the old harness burned and replaced.

Heres why.

1. The vehicle has a lot of work done to the engine. From the aftermarket gauges, and the ports added, for oil and coolant which also is wired also with the light dimmer switch, as the dash was put back together but as you'd expect, it was done to a pathetic extent.

2. There is, and I am not kidding- nearly 80% of the entire harness cut, starting from alternator then the HEI under the hood, to under the dash casually let hanging, the main gromet in the firewall might be missing.

3. Theres a rubber vacuum hose, in a state that looks like it was exposed to flammable combustion temperatures.

Sorry but I had to. It reminds me of my 88 CSC, mine was actually worse than yours. I have never seen so much cut, almost all the CCC wiring and burnt wiring on one vehicle. Another reason why it had to go and why I don't miss it.
