I have a couple things I’m curious about but each on their own is not enough to warrnt a whole thread. So I figured I would put them all together.
1st question. Is there a data buss I can tap in a 96xj? I have installed an overhead console from a 97? Zj and it works well enough but I would like if I could get data from the ecu to show trip mileage, mpg, miles to empty etc. I have read the overhead console write up and it has lead me to believe there is a buss somewhere I can tap but I don’t know where that is.
2nd question. What degree shim do I need for a 4.5 inch lift and no crosmember drop? I am removing the drop and I need a new shim I believe.
Lastly. Does anybody know if it’s legal in mass to delete the tail pipe and dump the exhaust right out the muffler before the rear axle.

Any help on any of these would be awesome thanks!

I have the BCM, and the ext temp probe so It can display the ext temp. I just need a data buss to feed the bcm
