Well I still don’t understand how twisting them together leads to poor connections and melted tape. For the lulz and I’ll probably get hate for this since my wiring is the Caitlin Jenner on this site, I used duct tape because A I don’t have some weird ambient heat under the dashboard, B I’ve never seen tape just fall apart from the “heat from wires” if taped more than 1 pass around the wire and C 99 percent of the wiring I have it leftover from my last swap which means it’s held up fine with no signs of degrading. I don’t think electrical tape is this sh1tty home use only tape either. The factory loom is covered in electrical tape it holds up fine to engine bay heat for 20* years. Not saying you’re wrong, just saying I still don’t see the issue with using tape over 10,000 butt connectors and shrink tubing. I’ve used shrink tubing on the distributor connections but at some point I just didn’t see how it would be any better than tape since it was going to be shielded and taped anyways. ALL the wires I have taped are in the same place as the factory loom was so unless there’s some other issues with the factory loom I don’t know about I think I’m fine and I think I can offer wiring advice because I substituted shrink wrap for tape. I’m doing the same thing you guys are doing, just with tape. Also this giant pieces of tape sticking out on top of my ecu, those are labels and not actual connections. They had to be hardwired in. Everything else was tested for continuity, twisted together and both ends of the wire were taped together at the joint making a strong connection. The tape is easy enough to take off but you have to try to remove it. It’s not going anywhere anytime soon.
