I was lucky, when I pulled the three connectors from the firewall for the very first time the connectors looked great. When I installed the new harness connectors I used plenty of dielectric grease before plugging them in. No issues at all.
Hey PJ724, this is how the factory placed my connector, buried under the coil down at the manifold for 43 years. Surprisingly it was not brittle at all, in fact it came apart easily. Lucky I guess.
I understand, just trying to show you how my harness was. My factory one was 43 years old when I restored my 73. Because of factory A/C wiring was included, I decided to go with YearOne. Never knew about anyone else at the time.

It's best to purchase new. I purchased mine from YearOne. M&H builds them to OEM specs, it's a plug 'n Play harness with correct connectors.
Worth the money.
