How hard is this to do with the engine still in the car. I want to twin turbo swap can i buy the tt wire harness and just leave the plugs that have to do with tt related things unplugged. Also is there just one wire harness from the engine that goes behind the fash for all the inside accesories or is there another harness i will have to replace the one that connects up to the gauge cluster radio heat etc.

seriously nobody knows this? Anyone whos done engine work or swaps does not know the answer =/

bump anyone??

I've never pulled the motor, but I'd venture to say it's pretty difficult to get to the harness. To pull the plug through the firewall, it needs to be depinned, so I'd guess you would need to have the engine out to do the wiggle room.

its almost impossible you have to get a saw in there and cut a bracket to get the harrness through firewall

Does the main efi harness connect up to all the front interior electronics and the fuse panel on the kick panel. Or is there another harness that connects to the front inside electric? Im asking this because im still having electrical issues with my car not as bad but a lot of problems and am hoping by te summer to be doing an engine swap so i want to eliminate my poor engine and poor electric at the same time

ther totally diffrent. the main harness it a pita more than efi

whts the inside harness called? I will need to replace both =[
