How to install fuel cut off switch on 89 NA?

Cipher

Look up under your drivers side dash. On the right side of the steering column you will find a relay w/ about 6-8 wires going into it (the relay will have a yellow "connector" on it). You should see a black wire with a white stripe comming from the relay connection. Cut that wire and splice a switch inline with it. In other words, after you cut the wire you will have to run anlength of wire from BOTH black wires to a switch (2 pole, or 3 pole if you want an illuminated one).

Don't know if that helped, but it's how I did mine. There is a post somewhere on this forum with pics and a writeup.....

How do you use the switch? I will turn the switch off and let the car die on it's own. This will relieve the pressue in the fuel lines. If you turn the switch off after you turn the car off you will still have pressure that will cause the injectors to leak (that is the main point of having the switch there).

If you're doing it right, I would say you have either a coolant or oil leak.

Some people like to crank the car before hitting the switch and then hit the switch mid crank. I just hit the switch right before I start the car. Its a metter of preference I guess. I agree that you gotta let the car stall though.
