I am no expert on the efi by any stretch, but if you get into it and have questions, give me a shout. I took the wiring diagram and Pinout diagram for the donor harness and removed everything that I couldn't use for my jeep. Cherokees have lots more systems than cjs. But I did gain several relay circuits in the PDC. And the harness became much lighter quick.
Largest word of caution...I cobbled mine together from parts that I bought cheap from several sources, such as a complete siezed 4.0 motor from a 2001. That yielded a very desirable intake design. However, the throttle body was different from the 93 Engine harness, so it was swapped for a 93. Many of the sensors from 92-2001 look the same on the business end, but the plugs changed quite a bit. I still have a box full of sensors that were either from the 01 motor or picked at the junkyard. Take home message, get on Craigslist and buy a wrecked and running jeep w a 4.0 and strip it. Part it out or else roll it across the scales for $11/cwt.
I don't actually live in TX, but my in-laws do, up in Allen. My CJ is patiently awaiting my return from Okinawa in Alpine, TX courtesy of BioTex (another JF member). Take a look at the CJ Express thread in my sig to see how it ended up there!
