I got an Apexi multimeter and fuel piggyback tuning computer for my 1994 celica with a 5sfe in it. It has the wiring in the manual for alot of models (even celica 00-up) but not for mine, i know mine has everything it needs because i've cross referenced the wiring diagrams in the apexi manual to those in my haynes guide and i found everything. The only question i have it the option of what type of air sensor/meter does my car have? it gives options like MAF and rb26det(being one connection for a specific engine) and a karmon sensor. What type does my car have and what are they called on the wiring diagram for the stock ecu? thanks alot, any info is appreciated
