I did an engine swap on my 93 Wrangler from a 2.5L to a 4.0L. Do I need to change the underhood fuse block and harness to a six cylinder one?

Here's what one guy had to say on a Jeep forum: The only way to do it is to find a parts jeep with the drive train in it that you want. A rusted out one or a wrecked one with low mileage,CHEAP. Then you are going to need the longer fuel lines,6 cylinder radiator,modify your exhaust, move the motor mounts,swap in the ecm and harness. Now your are ready to bolt in your 4.0,and transmission. You also have to use the donor jeeps cross member. This is how my buddy did his. He figures he has about $1500 into the swap. He paid a $1000 for the donor jeep,(rusted out 94' Sahara with 60 k.) this seems like a lot but it had a clean Sahara interior,and a nice hardtop. Between 40 and 60 hours labor doing it. Came out nice ,4.0 with 4.11's rip. I have been thinking about it to, but for the same money and time you can swap in a fuel injected V8. But if you can find a similar donor jeep for super cheap,it's almost worth it.
