Have had lots of interest in full Motorsport Spec harnesses which are still a few months out but in the meantime I’m offering stock B5 S4 manual APB harnesses that have my 2.0T Coil/Injector harnesses ($550 value) installed, any repairs, replaced any suspect connectors, and deleted EGTs, rear O2s, Stock coil/ICMs, and stock injector plugs.
For any repairs I cut as much of the stock wiring out as possible, splice in Tefzel wire, covered with DR25 sheathing, with new OE connectors and boots.
I also add a pigtail to add your widebands 0-5v to rear O2 for logging purposes.

All harnesses are tested in my car prior to shipment

Lead time is about 1-2weeks as of right now.

Price is $1,000 shipped/paypaled plus a core harness or another $100.
