Re: 83 Chevy C20 Suburban 454 engine wiring
I have not traced the tach wire yet....but this suburban is pretty original and I don’t think someone ripped a factory tach OUT of this truck. I will look into it more though.
Here is a pic of the electronic solenoid in question. It is 2x2x1 or so. Bolted to driver side valve cover. Emissions equipment related??? After looking, maybe it is not related to the cruise control.
