As title suggests what is the easiest method to fit a EF ECU Coil pack set up into a Boxcar

Have got the entire EF ECU , BCM and Dash + fuse box + loom + heater box+ Engine bay loom + Engine sensor loom etc

But kind of have lost motivation and don't really want to also pull the dash out is there any way around it as i have heard fitting up the EF dash can be a pain to physically put in needing mods to the mounts is this correct?

I would love to be told its as easy as just setting up the ECU in the kick panel and at a later date connecting up the BCM for the guages etc etc ( cars for track burnouts only so not fussed on guages etc they can wait


Thank you in advance

why going for coil packs and all the effort for a burnout car?
