I used a harness rebuilt by a firm in Utah: Rush Power Systems. The harness came back better then stock (over engineered). It was also checked and QCed several times before being shipped back to me.

The glow plug light on the dash now comes on and stays lit for longer then pre-wire harness replacement.
