Re: 1966 C1434 SWB Custom Cab
Added a check engine light just in case something is wrong the computer can let me know. I used the factory over speed lamp location for the MIL (check engine light). I just got a pigtail for a 194 bulb at O’Reilys. Hook the brown wire to the ignition lug on the back of the tach (pink wire). Hooked the black to the computer red connector pin 46 which is the MIL control. Works perfect. And I have a clean bill of health I guess because the light turns off as soon as the engine fires up
