So i bought a VAFC controller for the SiR. Dont have the manual, and found one googling for hours finally in a nice .pdf file. The install is fairly complex, but not for a buddy of mine thats very good with wiring cars. What im also looking for is a step by step install guide write up someone may of made that makes the install a bit more clear. (mostly for myself) Some of this guide is very confusing and doesnt exactly show/explain in detail. Heres the link http://www.turboborisov.com/vafc.pdf So what I wanna know is the 3 wires to the VTM,VTEC solenoid signal and the pressure signal... do i need to run those wires into the motor bay or do I connect up with them infront of the ECU? Do I have VTM, and what does it stand for? Im running a 2000 SiR with a b18c motor, and PR3 (obd1) ECU. So when im deciding what wiring diagram to use, should I be using H2-a? It matches the motor but im just worried since im running a b16 ecu. However its all the same wiring really. The car is OBD2, but im using a jump down harness and using an OBD1 ecu and motor, so when splicing these wires, I would think you need to splice above the jump down harness, but just asking to double check.
