I recently contacted M&H Electric Fabricators about a Cruise control harness for my 1979 LeMans. They offer both 1978 & 1979 for Malibu. Would anyone here specialize in the older cruise systems & know the differences in the Wire harness between those two years? (Different site but same product) Cruise Control Wiring Harness, 1978 Chevrolet Malibu If you wanted to see for yourself. Would this be the item that connects to the Brake light switch or where? My car is Non-cruise and i am trying to adapt the original style which would've come with it. (Inner fender transducer). Trying to find someone to help me out. Thanks.
