The reluctor wheel/pickup still works. That's why you connect the magnetic pickup's wires to the MSD box. The reluctor wheel/pickup tells the box when to fire the plug. In the unmodified RTR distributor the pickup was connected to the module and served the same purpose.
per page 11 of the msd 6201 instructions you do not do anything to the distributor internally connect red to keyed power, orange from dist. to whit on 6201, distributor black wire to ground. its all there in the instructions if you read them.
I think they call both the 8360 and the 8361 "Pro Billet". I think they share all the components except that the 8360 "ready to run" has the module. 8360 has 12V in and coil + and - out. 8361 has magnetic trigger out only.
If you were to buy a 6201 box and also wanted to buy a distributor, they would recommend an 8361. What I posted previously was how to make an 8360 distributor act and wire up like an 8361. You do not need to do that - just wire up per the instructions posted. It is good marketing and engineering to be able to add the box without modifying the 8360 distributor. The 8360 distributor costs about $75 more than an 8361.
For those who may be interested. I got an email back from Holley.com. I emailed Tommy Nicholson, he is a Customer Service Technician. Contact: (915) 855-7123 ext. 2752. He said that my MSD 8360 ready to run distributor will work with the MSD-6201 6A Digital Box and the MSD-8203 Blaster 2 Coil. He even included the wiring diagram shown below that illustrates how all the wires should be hooked up. Click on the diagram to enlarge it. Thank you all for your outstanding support. Aloha, Tommy.
