Tachometer Adapter - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I had stated probably wrong that my factory tach would not work with the LT1 I have installed. It has the computer hooked to it. Ol Blue gave me some feedback stating that someone by the name of Williamsons might be able to help me out. He referenced Hemming Motor News. I performed a search of the site which didn't help me out. Anyone have any info on this subject? I am real close to getting the 67 on the road. This would help me out tremendously. Thanks for any info you can share. Wootdog

If you are using a stock harness the wire should be red/black at the ECM! If you are using an aftermarket harness the manufaturer should be able to tell what wire to use.
