Evaluating old Wiring Harness

Personally, I would call Jamie at Mega Parts, he is less expensive than Year One, same M& H harness, even on sale, PM me as to why, not saying here on this thread. Or, call Evans wiring. Both are top notch. Remember, most harnesses on Mopars are individual. Wiper, trans, engine, dash, tail light, etc. Some 3 or variable speed wipers have the harness attached. On the three cars that I own, 2 had complete wire replacement, hacked and brittle insulation. One was excellent except for firewall forward, cracked insulation. Use dielectric grease to protect all connections. The last sentence is just what I do.
