Accel Super Coil

605 2
Hello, I know that this has been asked before, but the search is down. I recently recieved an accel super coil for HEI ignition. I took it off the distributor cap and seen that it was a red and white wire one. Both of my distributors for my chevelle has the red and yellow wires. Can I use the coil and it be safe? What are the differences? Please let me know. Thanks, Eric
