Ignition Wiring Harness gets HOT??? (Yellow Wires)
Hello, First of all I would like to Thank All of you who has read this and are trying to help.
I have a 1988 Mustang GT 5.0L, It's been converted from Speed density to MAF and has a MSD 6AL Box and upgraded to a 130amp alternator from a newer GEN.
Before the upgrades I had this problem and continue to have this problem after the upgrades. The ignition switch has been getting HOT and falls apart. I have replaced the ignition switch twice and continue with the same problem. This time around I have replaced the ignition switch and the starter solenoid that is mounted on the fender and I continue to have the same problem. I have noticed that the two yellow wires that are on the harness are the ones that are getting hot and the plug has started to melt. Does anyone have any sugestions as to what should be my next step?
Thanks Again

Your first plan of action should be to move this to the correct section of the forum. I hate to say it, but with newer cars (you're in the 2011 5.0 section at the moment) most owners will not be getting down and dirty with their cars, hence the post above mine.
As far as your problem, as you probably guessed it, you seem to have something wired wrong. The starter should only be getting power when cranking. With your issue, it appears you have power going to it constantly, causing it to over heat and fry.
I'm not familiar with the layout of the wiring harness for anything but RX7's, so I would definitely recommend taking some pictures / drawing a detailed diagram of how you have it setup, and post in the other 5.0 forum.
