Genuine Mopar P4120534 Chrome Electronic Control Unit

I purchased the Electronic Control Unit for my husband's 1970 Dodge Challenger (Special Edition). He was able to replace the old control unit with this one without difficulty. He replaced the part himself (he is not a mechanic!) based on advice from friends and a little research on the internet. The Challenger has about three test drives so far and all is going well. He bought the part in an attempt to address a problem he had with starting the car. After years with no problems, the car just would not start one day. The hope is that this will fix the problem. Anyway, so far, it has worked! He recommends the product. Delivery was timely and the product was as described.
