Magnum and Wiring Swap
autopar3000 is correct on the fb magnum swap forum. I belong to that forum and the guy that started it, Kerry Kinser, is a wealth of kmowledge as are a lot of the top contributors. KK makes easy to use wiring harnesses for you swap. I and a friend have his 1st design but later ones are really good and only use 3-4 wires to start a transplanted magnum.
