Jb3 to jb4 upgrade

Cromartie84 · 01-17-2012, 10:28 PM

So do I need to send the jb3 in and they send a new jb4? Or do I just pay the 150 and they send the jb4? How does it work?

do you have the PnP or the pin out JB3

Found the info. Anyone done the upgrade at home? Not the best with wires...

I have the pnp

Simple and i suck at wiring. Harnesses are very friendly

If my DPs show up I'll be performing the upgrade from my JB3 pin-out & installing the DPFix while I'm at it. The directions for the PnP don't look bad but not having specific directions for the pin-out does make my a bit nervous. Hopefully the #'s & such match up on the stock connectors.

Performed the upgrade yesterday; didn't get a chance to drive it yet since the snow hit but a separate set of directions for us pin-out guys would be nice. After cross referencing the original JB3 pin-out directions & the new JB4 PnP directions everything worked out (I think). Idle is smooth, car revs fine with no hesitation but hopefully I can get it out today to test it out. Just make sure that you pay attention to what slots you pull the JB harness wires from because the originals need to go back to the factory positions. I hope that makes sense to those of you that will be performing this upgrade with the pin-out.
