New to forum, and hoping I can get some help. Currently working on a diesel swap into an FSJ Wagoneer. To make the project a bit more exotic, I'm also swapping in dash/gauges from '06 Grand Cherokee. I've hit a snag. In order for the fuel gauge to work, modified the sending unit to be the '06, but can't figure out how to wire the sending unit into the '06 dash wiring harness.
Anyone out there have wiring schematic for '06 Grand Cherokee?

I'm pretty sure the 06 cluster requires the body control module and ECM to function.

I would skip using anything new most use a ecm for everything its a nightmare.Keep the stock dash you can get a gauge panel plate from bjs off road and run any aftermarket gauges you want with less headache.

'06 does require body control module and ECM, which I have. Plan B is to surrender on the OEM cluster donated from '06 and build cluster using aftermarket gauges...BUT before I give up, I would like to try to sort this out...I have the wiring harness from the dash (includes pigtail for the instrument cluster) & have the pigtails that plug both into and out of body control mod...the problem is that the wire colors from sending unit (Blue/White & Grey/Blue) do not match any of the wires in any of the chassis wiring harness. Anyone have wiring schematic for fuel sending unit of '06 Grand Cherokee (Hemi)?
