Need help wiring SAFCII into VPC harness

[akotten]

OK, so I wanted to wire up my SAFCII into my VPC's harness and prepare it for installation. Only thing is, I'm still a bit confused as to which wires from the VPC need to be intercepted by the SAFCII. My VPC only has a blue, red, white, gray, black, and brown wire (these are what the VPC plugs into). On the plug-n-play harness, there ARE a few yellow wires that stick out the side because they have fuses or transistors in them (little plastic enclosures).

Any help is greatly appreciated!

This is specific to the Supra installation, but the general principal is the same:







The VPC output wire (should be yellow) connects to the SAFC Input wire (white); the SAFC output wire connects to ECU harness the same as it would without the VPC.

If you have the plug n play harness, you may need to disconnect the yellow Output wire, as it comes pre-wired into the harness (thus 'plug n play'). That's the way I installed it on my Supra -- works perfectly. I leave the VPC zero'd and do all of the tuning through the SAFCII

I would have replied to you on 3si previously, but I'm suspended for a week.

Does this harness look familiar?
