Don't mean to revive the dead but I'm planning on upgrading my wire harness also and I checked out both of the harnesses that were posted above. My question is are they the exact same harness and the only difference is price? The amazon harness says that it will not fit my 98XJ but the one from eAutoworks says it will. Are these 2 different ones or the exact same kind and amazon is just being weird?

 

Those probably are the same harness. The harnesses are not made to fit any one particular vehicle. They're just generic relay harnesses. Amazon doesn't list it as compatible because there's just no way to list all the vehicles it's compatible with.

HOWEVER, there has been a pretty good development since this thread was posted four years ago. A lot of people have been having good luck with this instead:

For less than $20, it's hard to beat this. Unlike the Putco harness, it has ceramic connectors. So far it doesn't seem like there have been as many complaints about the relays failing. There's nothing in the Putco harness that justifies paying twice as much for it as this harness. Next time I'm in the market for one, I'm going with the Ebay harness.

By the way, as long as we're resurrecting a dead thread:

No, THIS is the best you can get:



It has three relays instead of two and is long enough to mount the relays on the rear firewall. Is it worth an extra $100? Only in the most extreme duty circumstances. The Ebay and Putco harnesses are almost always good enough. But if money's no object, it's definitely better made than the cheaper harnesses.

 

Cool thanks for the help, I just ordered those! Next is headlights.

 

Why the harness doesn't come with the fuse assembly inline I don't know. What amp fuses do I use between the battery and relay?

 

double post-sorry

 

Most of them have fusible links because they're trying to produce them as cheaply as possible.
