I'm a bit late to this party, but bear with me. Rebuilding, the harness may be a weekend event, but what would be the harm in fiberglass wrapping the rebuilt harness? The way I understand it, heat creates resistance ad resistance creates heat...would it hurt to minimize the affects of ambient heat at the get go?
