3B,
I called them too. They told me that 30370 harness did not have the diode and gave me the spec's on the diode. Picked up the diode last night installed it and all is fine now.
Thanks for the help, another problem solved by the great people on this site.
The diode that Autowire uses is 6amp, 400v, NTE5814. I installed a 6amp, 600v, NTE5815. Could not find the 6amp 400v, NTE5814, but the NTE5815 should still work fine. These are actually silicon rectifiers
