i have a 88 vert tring to make a fuel cut switch but i read in a post there is a fuel relay under dash and it is yellow plug w/black base and it has 5 wires it said to cut the blk/wh wire but on my car i have seven wire and 3 are blk/wh 1 is all blk the other is blk/wh and the other is blk/wh w/ red speck on it which 1 do i cut into

 

Okay. You should see a white connection with a totoal of 5 wires coming out of it. The black/white wire is in the middle. Find this before you cut anything up. You may have to get into some really strange positions to do so, but you need to find it to be sure you have the right one. Once you have loocated it, just cut into the wire and make your connections and bingo.
