Haven't bought it yet BUT: Check out the BleepinJeep YouTube channel, Matt does a great step-by-step guide Exactly Cherokee setup Except also, don't buy battery cables, use spare jumper wire wires (cut clips, already dyed, cheap) I just wrote this to help folks, I'll update as soon as I buy

Not that painless. best battery tester

This kit was a headache. Hooking it up to the starter solenoid was the biggest pain. I ended up having to order custom made battery cables. One of them was 8 feet long from starter to shift cylinder.

Pros
  • looking forward to
Cons
  • modernity

Pros
  • Good workmanship
Cons
  • Not as good as written

Pros
  • special offer
Cons
  • sad packaging
