Testing plug wire ends
So I bought a set of Beru wires without ends, and am planning on redoing a set of wires. I have read that the ends last longer than the wires, but since I am taking an old set apart, and adding new wire, can I test the ends. I thought I read that there is a set resistance, so could I use a meter to check capacitanse?
I couldn't find it doing a search.
Thanks,
Emerald

Emerald, Plug wire resistance should be about 3kOhm end to end
Can't recall what the resistor (ends) alone should be but they are the vast majority of the 3K Ohm

My experience is that the plug connectors don't last any longer than the wires due to failures of the internal suppression resistors.
For this reason, I always replace the wires and connectors at the same time,...
I find too many open ones and they will cause a myriad of small misfires when they go bad.

My experience (albeit much, much less than Steve's) with the 2 964s I've had before the 993 is that the plug connectors go south even before the wires.
You also run the risk of damaging the connectors when replacing the wires. It's just not worth it IMO. Get the whole set and be done with it.

Indeed, they sure do and thats been my experience with these since 1974.
Thats truly golden advice. I cannot believe some "Einstein" thought it would be acceptable practice to place an electronic component (the internal resistor) in the hottest running part of an air-cooled engine (the heads).
