Lexus is300d Compound swap.
Lexus is300d Compound swap.
Speedo will be wired to abs, rev counter is 1 wire so either alternator tap or tap into the crank sensor with an arduino.
I plan on using an arduino to display egt, boost and egp anyway.
The coolant, oil pressure, oil level, battery light are fed through a multiplexor. So these will be wired seperatly.
