Ok So the dash bolts in, but what about wireing, I have bolted in a el 4.0L engine including the BBM manifold, To put the dash in should i get the complete wireing harness from headlights to dash including BCM & ECU, if i do this how will i go with the wires to the back of the car EG fuel pump, tail lights, ect, my dash is already out as it has been going on for nearly 12 months 2nd time car has had huge mods i startered agian so now i want to get it happening, any help would be great

Been there, supervised doing that!
Yes, get the whole looms from an EL. You can chop the old wiring (to the boot, doors etc) and connect it all to the loom to save rewiring the whole car.
