Hks Vpc ?
This is DaveH's wiring HKS VPC wiring diagram for the MKIV na-t supras. Will this same wiring diagram work for a 1995 Lexus SC300 5 speed NA-T & VPC with MKIII 550cc injector chip?

Jacky, after looking at that diagram a few times.. something doesnt seem right. Why is the grey wire from the VPC going to pin B66 (KS.. i assume is Knock Sensor) and why is that same wire the one that is bisected for the pink and orange from the SAFC?? The pink and orange are for karman maf.. which is the old setup for the stock MAf.. the VPC is MAP or speed density and should be using the yellow and white from the SAFC. This is beside the point, I'm just wondering why it shows to cut a wire that is apparently attached to the knock Sensor and not the MAF signal wire.?? 
if i read it correct, the red wire on the vpc is 12v switched power (B+), the white wire is a tach signal.. since the green from the SAFC intersects it.. the grey one.. well i dont know what the grey one is supposed to be. anyone care to chip in here.
to answer your question from earlier jacky.. i guess you would have to compare the ecu pinouts of the mkIV supra and 95 sc300 to see if there are any pin differences. i think the 2jzge was interchangeable..ecu..etc. so you may get lucky.
