If the wiring harness is anything like a MK VII I'll agree... It includes the ABS system, air suspension, engine control, lighting, etc in the underhood harness... Plus it's about 8-10 ft long, as it travels down the left fender apron, wraps around the radiator support, back up the passenger side and into the passenger compartment... I bought one for a 5.0 swap into a 4 cyl Turbo Coupe T-Bird and wound up just using the engine(actually only short block)... Luckily I found a Screaming deal on a '87 5.0 T-Bird with blown 5.0 that donated it's harness and all the little things needed for this type swap... Those included motor mounts, throttle linkage, A/C compressor & lines, AOD shifter, plus it had a fresh radiator, battery, alternator & starter(all in a $100 car)... Luckily the ABS & ride control harness are a separate harness in the TC, still I had to build a interface harness to connect the 5.0 engine harness to the Turbo Coupe body/chassis harness...
Yeah, I went through a similar mating issue when I swapped the 302HO into my '88 F-250. I used the harness from an '86 Mustang. Was a lot simpler than trying to do the Mustang gauge cluster though, LOL!
