i need to know the voltage requirements of the JDM electrical system.

a TPS scan procedure should tell me circuit voltage of the V4, correct?

i need an easy way to tell if it's 5V reference, 12V ref., or 7.5V(doubt it). would all other sensors be the same also?

im trying to use some usdm A.C. bits, and dont wanna fry anything. help is appreciated greatly! -keith

Moving this to the Conversions forum, I think you'll do better over there.
