Hi all,
So I need to replace the coil wires on my 05 b6 ultra sport 1.8t. They're brittle and cracking making it run bad and throwing CEL' s. Got a replacement wiring harness and it doesn't look like a simple swap. I've read some old posts on here and some said it was a plug and play. My replacement harness is about 3 feet long and has about 4 or 5 wires coming off of it that need to be plugged in too. The longest wire looks like it may go into the computer box or into the passenger compartment following the wires that's all bunched together under the rubber surround. Is this the case?? Is splicing the way the go? Any help would appreciated!

Thanks!
