NHRA RULE 8:2 In categories that permit a delay device:No other wiring shall be connected directly or indirectly between any other part of the ignition system or any other devices ( such as data recorders, tachometers, suspension components, fuel-injection system, etc)

If you're running NHRA track I'd say you can't. If you are running an outlaw track, it's up to the track. Don't know about IHRA.
