Just bought the Big7 cable kit for my 93 yj. My question is about the existing cable from fuse block to alternator. The new cables come with 150/200 amp inline fuse from battery to alternator. What do I do with the old wires coming from fuse block to alternator? Thanks in advance

I just zip tied it out of the way. It is no longer live, but I did not snip it off in case I ever wanted to return to the standard wiring/fuse arrangement. You may also find that the one for the alternator ground to the engine block is too short to use. Overall I have been very happy with the wire set.

OK. So do I take the fuses out of the fuse box for the alternator?

I attached the large replacement fuse provided to the jack location.

I still have the OEM cables on my '92 and was thinking about the internal corrosion on them and replacing them anyhow. I've had several cars and a tractor where the battery cable was down to one corroded strand in a bunch of white powder hidden inside a clean cable shield. You'll never know until you cut it open.

The install looks very straight forward but seems like a lot is bypassed with this new kit.

Question: Currently the red cable from the alternator goes into a big sleeve all the way around to the ECU on the drivers side. So your saying all that gets eliminated by the short cable to the new fuse block? Wow, I'm glad some electrician figured this out.

Since I just have a classic daily driver with LED lights I'm going with the 4ga wires.

Thanks for posting this.

See steps 9-12 through of the instructions for the explanation.

Yeah I saw that and followed along to see what they're describing. I'm just saying it's a long way to go from the alternator to other side of the engine compartment the way the factory did.

I'll take another look at it but not that it makes any difference.

Edit. Nevermind,. I looked inside the loom and it's a different wire.
