Hi, I am new to the forum and recently did a 347 swap into my '91 fox, and when doing so, I replaced the ECU with a Holley Hp EFI system. I have the car running and driving, but the radio does not turn on. I believe the radio got its power from the old ECU through its system of big red wires that all join together. I would like to know if anyone has had this issue already before I start digging around and cutting up wires. Any help is appreciated, it is an aftermarket radio that was from Crutchfield so it came with the necessary harness for direct fir into the factory harness. Thank you.
