hey...i purchased an 88 supra turbo...i dont know a lot about toyota, (my other car is a 240sx). anyway, im missing a few wires from the previous harness (a sensor or 2, and the guages)...and i have 1 or more vacuum lines not connected. i did some research and i know the fuel pressure up vsv is 1 of the lines that isnt connected...my question is...could that be the main reason. What other things should i look for...and does anyone have any good detailed engine pics...and a pic that shows where the fuel vsv actually is mounted too...the vacuum diagram (drawing) doesnt really help with that. thanks.
