I have been trying to find a engine wiring diagram for a 500Bull Dog 540 v8 !990 throu 96. The engine that uses the electronic box that looks like an MSD unit. I have been looking all over the net. I am using a brand new old stock wire harness and trying to wire it to a 581cid engine with all MSD ign components. Is there anywhere it can buy a schematic without having to buy the whole service manual. Thanks for any info
