Well, I went to fastlane and didn't see two options to order for the 140 regulator, just one which was not the Behr. I called philip and he had a Behr in stock so I ordered that up.(Cost about $200.00) When it arrived, it didn't have the wiring extension that seems to be the implication in the e-mails above. I agree, it sounds great, i.e. remove the extension harness for the 140, keep it on for the 210. Well, I just ended up splicing in the extension on my own using the wiring harness from the old regulator. Everything works great. Thanks for the directions and diagnostic help.
