That's just the thing I've been asking myself these day's, if I go for a 'modernized' engine with the OBD and the works, how much more of a hassle is it against the non OBD engines with EFI. I know there must be a series of exhaust sensors, a TPS, MAF, knock sensor and maybe 2 speed sensors like in the WJ. The question is how is it integraded into the rest of the car, is the wireing all in the front and everything behind the firewall just the dashboard and lights. The ideal setup would be to remove all the engine harness untouched from the donor and hooking it up to the things that matter in my truck, like +12v, starter, ignition and so on.
I know it's not quite that simple but you catch my drift. Also what's to be gained by going that way? Will I be able to remap my ECU with a SuperChips module and will that affect the shiftpoints on the transmission. If that's not the case the pre OBD is clearly a better choice considering price and availability.
