MSD ignition install

MH through Year One make some of the most accurate harnesses
 I would still talk to Roseville first though , you should get a discount through Dave but I am not sure what his source is .

Using the Iron dist drive on a billet cam will chew each other up , bronze is somewhat better but only lasts about 3-4 oil changes & you need a new bronze gear

I'll give roseville a call and see what they say if I got a YO engine  harness for a 70 challenger with electronic ignition and 440 would it work in  my 73? Trying not to hack a new harness if I can get a plug and play that'd be great

no the 70 wiring is in different positions on the plug , wires would need to be repositioned , not that it is hard to do that . They should have a custom harness for the 73 440 with electronic ign .

Got a wiring harness setup from roseville got here in no time and looks great laid it out in my engine bay and seems good but some wires I'm not sure where they go only thing I wish I got with this kit was a instruction sheet that says which wires are for what the color coating on the wires seems to match the stock wiring anyone have a electrical diagram of the stock wire colors and what each go to that you can post up to help me out

Just replaced my harness today with a new one fits great was a  plug and play install have some questions now about  hooking up the msd ignition box  what do I do with the 5 prong plug that attaches to the mopar orange box just unplug it and leave it alone? With the msd can I get rid of the  2 white connectors on the ballast and eliminate the ballast? Also was the factory harness for the coil and altetnator ran along the inner fender or beside the valve cover looks like my original harness was cut and lengthened to run down the inner fender when compared to my new harness I'll post up pics of the new and old harness when I get a chance

yes you can ignore or remove the 5 pin plug for the ECU , the ballast & connectors can also be removed , you need to connect the small red trigger wire for the MSD to the Brown & Blue wires at the ballast to get it to start & run .
 the wires for the Alt ran along the valve cover , do not lay them on the manifold or they will melt & short
