I'm going to reuse my wiring harness while swapping engines on my '88 NA S4 convertible because the one on the replacement engine had been altered. It looks like I have to remove the intake manifold because some wires go under there.
Anything I got to watch for? Can I reuse my intake gaskets?

 

No much to watch out for... just remove the top half of the intake and redo all the wiring... Great time to really clean everything. No you won't be able to reuse the gaskets... also the PERFECT time to replace the pulsation dampener...
