the wireing ether isn't as bad as youd think or worse than your worse nightmare depending how you look at it.
there is a lot of wire to deal with a lot of it is 0.35mm2 so it's fiddely and a pita to work with.
the ecu needs to be craked to deal with the immob as no clocks ect = no go once the immob is gone it's a lot easyer.
things that you need to look out for are things like the switches above the brake and clutch pedal. if it thinks your brakeing it won't rev, if it thinks the clutch is down it won't rev out, so you'll be linking a few pins.
joining wires pay much attention to the pin in the ecu connector if it's a gold one you really have to use gold plated crimps else it will ghost faults at you, on some of them they'll ghost if you solder them. ideal solution is replace whole wire.
fitting the engine itself is a piece off piss, some brave pills are needed to do it right tho as you need to strengthen the inner wings and weld in pendulum mounts from a mk4, it really needs the 6 speed box as imo its crap with a 5 speed.
not a nicest conversion to drive in a mk2, yup its quick and uses naff all fuel, drives like a lumphammer as DH would say and its nose heavy. esp with the 6 speed box. recon it'll make the T4 go well tho
