installing gauges. . .AGAIN. quick question 200 1987

Sort of.

The clock gets a constant hot and a ground, and a dash light wire.

Constant hot might not be suitable for other gauges. For example, if you were installing an oil pressure gauge, you might not want a constant hot. There isn't any need to read o/p with the engine off :)

A better choice might be a wire that is only hot when the key is in I, II, or both. Example: the factory wiring in the Turbo for the voltmeter is only hot when in position II.

If you ganged it to the clock constant hot, the voltmeter would always read. Not that this is a bad thing, but it is one more (teeney tiny) drain on a battery that is not being charged by the alternator.
