Thanks Scott. Another thing I'll address on my conversion. That little ground wire. I'll make sure it, and others, are clean and in good shape. Worthwhile doing. Also similar is checking the donor wiring harness for fatigued material/loose spade connectors etc. On mine, I found at least 3 failing points. Neil.
