I want to lengthen the wire from the starter to the battery on my '90 Corolla so replacing starters won't be such a pain. The wire is the same gauge as battery terminal wire and packages of that are marked "4 ga." What's the best way to splice such wire?
I went to an electrical supply company and they had splices. The splce marked for #4 was too small, so I got one for listed for #2-#4.
The splice is a metal cylinder. It has no insulation, How is the splice supposed to be insulated? Ordinary shrink wrap looks too flimsy for the job. I wouldn't trust electrical tape for automotive use.
How can such a splice be crimped? The cylinder is thick. It looks like it would take a tool with compound leverage to do a good job.
If I make the wire longer, it will need to be tied away from the CV joint that's below the starter. What is used to tie thick wire? I wouldn't trust ordinary cable ties for this job.
