I just finished replacing the OE wiring harness on the '95 GTS with a new one made by Sean Ratts. VERY well made replacement. His directions for doing this (on Roger T's web site) are straight forward and very helpful. The car is 29 years old and 150K miles of engine heat. OE harness was nearly as rigid as steel!

I have limited mechanical capability and flexibility. If I were to do this job again on a late model 32V engine, I would drain the coolant and remove upper/lower coolant hoses. With large hands and stubby fingers, some of the access areas are a bit difficult (not sure whether I spent more time scratching my head for 'how to', or scratching the back of my hands 'doing'.

Car starts nearly instantly now, whereas it cranked for a couple seconds with the old harness. I was aware of 3-4 places where there was some significant corrosion on the copper wires of the OE harness.

The best time to replace the FME (Front Main Engine) harness is during a timing belt service.

The hardest part is always the p-clamp on the top side of the engine carrier.

Both my harnesses are replaced on my cars too. I happened to go with GBs harnesses as they looked basically stock, and I will one day temporarily export one of my cars, and I wanted things as stock looking as possible. But as I recall my decision process, I had the impression that Sean might have been using a little higher grade materials. My cars have 42.000 and 92.000 miles, respectively. There were no outward signs that this was really needed yet, but I just like fixing things that are not yet broken I guess...

One of my harnesses (the one on the 91 which was sourced in 2017) came with the unfused line to the ABS slightly too long, which required basically going all the way to the front area and then a slight loop back to the ABS. This was an irritant due to the fact that that line is so critical for safety. So, Sean's QC might be better... (Also, however, Sean called me a Democrat on the OT forum, so that's 1+ and 1- for him...) I check the line regularly and do not believe it will every be a safety issue.

I kept the old harnesses around just in case... for no real reason... Probably just to sell with the cars if I ever sell them.

I see that Kroon also has the FOE harness. Has anyone installed one? I see with the Euro at it's present conversion rate, it's around $670 with shipping.

I’ve installed a Kroon LH harness. I wouldn’t hesitate to install a Kroon FME harness if it was presented to me.

That said, I will note that *all* of the non-Porsche-produced harnesses I’ve installed have each had “niggling” issues that required rework in order for them to meet my obsessive perfectionist standards. And in each case it was a different issue.

Furthermore, the harnesses should always be “ohm’d-out” against the wiring diagrams on a bench.

Last, the 2- and 3-pin Junior Time connector bodies that were standard on pre-‘94 (-ish) 928s are no longer available. Expect that any harness you get will have the “modern” spring-loaded 2- and 3-pin connectors. This will cause fitment problems depending upon the exact location.
