I'm trying to install an HKS Fuel Cut Defencer on my JDM 1998 Supra Twin Turbo (with VVTI).

I looked at the install guide that's available on the forums but, it's on a non-VVTI ECU with only 3 connectors. My ECU looks much different. It has 6 plugs. See pictures. I need to find out which wires I need to tap into for pressure, ground and power.

Guide: HKS FCD Installation Instructions

Can you guys direct me to a schematic of the ECU wiring? I tried looking through the services manuals but didn't find it (I could've been looking in the wrong sections though).

Thanks for your help.
