JGREEZY Posted October 17, 2015 Share Posted October 17, 2015 Anyone one familiar with Speedhut gauges wiring on the 2JZ VVTI trying to hook up the tach. It looks like the wire I need to splice is missing or am I wrong. Also what type of adapter do I need for the oil pressure gauge Quote Link to comment Share on other sites More sharing options...
Geno750 Posted October 21, 2015 Share Posted October 21, 2015 So since you're using the igniter, follow option 4 from the directions. You'll use the ecu tach signal wire(should be pin 16), a 12v wire and the resistor they included with the gauge. Wire it up as shown in the picture.
