Just wanted to pass on some GOOD news regarding an aftermarket part.
Jim Carter sells a wiring harness on page 38 of their on-line catalog and I'm thrilled with it. The quality is first class and it looks very "stock" the way the bundles are wrapped. We've not had to add anything, splice anything or in any way make the slightest modification to get anything to fit or lay neatly.
Of course, these kits are for basically stock configurations with the only options being generator or alternator.
$210 each and highly recommended.
