Have vehicle computer wiring diagram. Is the cylinder head temp input a voltage or a resistance reading? I want to augment with Hydrogen "brown's gas" and want to insure the cylinder head temp is maintained in the normal range.

If you are refering to the temp sending unit, it works from resistance.
