767Jockey, I had mine originally mounted in the engine bay. After 2 1/2 years, it finally went out. Cause? MSD looked at it and said heat. It would run for a little while and then cut out. Wait 10 min and let it cool down and it would go for a little while again. Re-mounted it under the dash behind the glove box and have had no more issues. My coil is still in the engine compartmant.
Hope this helps
