FiTech EFI system
My buddy Larry's truck was triggering the MSD without cranking the engine. The shielding also fixed that. I shielded my magnetic pickup wires with aluminum foil and then wrapped a piece of stainless steel wire around the foil. I then grounded the stainless steel wire, the Fitech end to the throttle body mounting stud and the distributor end to the distributor body using a bolt through one of the unused threaded holes on the aluminum distributor body. I then encased the wires in covering to make it look better. I also made a metal shield to cover the pickup inside of the distributor (see my other thread). If I can help in any way PM me.
