2000 xj

I have a 2000 XJ Sport. I just picked up a TJ DANA 44 with an EATON E locker and 4.56 gears. The e locker didn't come with the wiring harness. What's involved with the factory harness? I see the directions say do not engage over 5 mph. Does the factory harness tie into the transmission to prevent engagement if going too fast?

The factory locker was tied into a switch on the transfer case that didn't allow you to engage it unless in low range. Buuuuuuuttttttt, this was a feature that reduced any liability due to people engaging a locker when they shouldn't. You can engage it at any speed without hurting it. The only thing you should avoid is engaging it with only one wheel spinning

Thanks for the info.
