Has anybody done the upgrade from the original (A000 158 40 45) resistor? Originally, the resistor is a tube looking aparatus with a 2 wire harness that is made on to it and is bolted at the bottom of the fans towards the passenger side. EPC shows a multiple supercession to two resistors (A000 158 37 45 and A000 158 39 45), a "cable shoe", A002 546 30 40, a bracket that apparently holds the resistors, A140 620 71 14, and nuts and bolts to put it together. I can't find difinitive info on how to wire it. The service manual says to cut the lead off of the old resistor, but then states that the new resitor is supplied with a lead as a replacement (the cable shoe?), saying to route the lead behind the LH headlight and connect it with a 2 pin connector. I don't see that connector or any connector all the way to the fuse box where it's wired to the relays. I'm to go ahead and order parts as even with the A/C on the fans don't come on at all until the the temp is 107°C, but the info is vague.
