sun super tack question
 

how do you wire it to a HEI distributor?
i see 3 wires on the back one says ignition, where does that go?
one says trigger, does that go to the distributor cap marked TACK?
and the last says ground, i think i know where it goes:icon_smile:
thanks

You should have four wires, red, white, black, green.

Red- to 12v source when key is turned on.

White- to light/ gauge panel circuit on fuseblock.

Green- to TACH on distributor cap, probably need a female wire terminal.

Black- ground.

Unless he didn't get a illuminated one, which is very rare now since pretty much that's the standard with gauges. But if that'd be the case, then he'd have three. What colors are they?

thanks guys for your help
