Shell and full THOR wiring harness swap after roll, please help finishing off!!

Hi all relatively new member but first post, rolled my 99 THOR and stupidly bought first donor I found, a 96 gems! Have swapped the shells over then had to swap entire wiring loom from THOR as different! Big mission but all done now, however I forgot to take a template of where engine ecu box mounts to bulkhead and can't find a picture anywhere? The 4 bolt holes no prob but just want to know if there are two holes or just one for the vent into passenger footwell?? Any pictures or advice much appreciated, also forgot to take note of fuel lines to charcoal filter under body as "assumed" donor would be in same place so I could copy routing but done that much other work I can't remember now..... gonna do a full write up of shell swap once she's back on road and have time..... cheers stu

Ps the tank is from my 99 4.6 THOR only got one line off that for fuel, two lines from engine, flow and return? But only two connectors on the filter thing and one large plastic pipe coming off looks like it's just a vent, two lines on filter marked tank and purge!? Once I got these pipes in right order can c if she will fire up as all electrics now work and cranking over.....
