12V mod

[91T breezen']

I wanna' do the 12v mod on my car to see if the idle loses the stumble that I've had ever since I installed the Aeromotive vfpr. I've seen the diagram for the 87-88, but does anyone have it handy for the 89-92? Or a photo showing the plug that you jumper.
Thanks;
Tom

On the passenger strut tower, there is the fuel pump relay. it's bolted to the fuel pump resistor. There are 2 wires going to the resistor. Jumper those wires. They're black with a red stripe if I remember correctly. You can't miss the resistor.

i did a writeup on this a while back. (it shows what to jumper, for just the 12v mod, and also shows how to rewire the fuel pump to an external relay. read up on it here:

Yes, I do have a gauge. I've been running about 44-46lbs on the Aeromotive. That is too much, yes? Dr. Injector said that with more boost, the stock Supra injectors are good up to about 50lbs. Good info, or BS???
