Start Enable Relay
This is the 2nd most common failed part of the VATS system. This is much easier to disable than the ignition switch.
Things you will need:
small flathead screwdriver
Philips screwdriver
7mm nut driver or socket
large butt connector or large wire nut
shrink wrap or electrical tape (if removing)
wire crimper/stripper/cutter (if removing)
The Starter Relay is located behind the DIC (Driver Information Center) Panel. To remove this, you will need to remove a few dash panels.
Removing the Gauge and Radio Bezel
Gauge Bezel:
Using the Philips screwdriver, remove the 3 screws on the door side of the gauge bezel and the 4 screws on the front.
Next remove the headlight switch knob. Using the flathead screwdriver, push the spring clip back into the knob and gently pull it off while still pressing the spring clip.
Tilt the steering wheel all the way down and then unscrew the tilt lever.
Gently pull the gauge bezel forward, up and out and set it aside.
Radio Bezel.
There is one screw on the left side, two screws on the right side, and 4 screws on the front, located at the center and bottom.
Gently push the dash pad up a tad and pull the radio bezel forward and out and set it aside.
Removing the DIC Panel
Using a 7mm nut driver or socket, remove the 3 small bolts holding the DIC to the dash.
Gently pull it out and let it hang down out of the way.
Behind the DIC panel is the starter relay.

Bypass Information
Bypass Information:
Disconnect the relay from the wiring harness. If the plastic piece it is mounted to is in the way, unscrew it and set it aside.
There should be 5 wires coming out of the harness. The color combinations are as follows:
|
Starter Enable Relay Wires |
|||||
| Pin A | Pin B | Pin C | Pin D | Pin E | |
| 1986-1989 | 5 DK GRN/WHT | .8 DK GRN | 5 YEL | --- | 5 YEL |
|
Note-1 Below: 90-91 information for reference only. Need to verify if correct. Note2 Starter Enable Relay located in different location than 86-89 |
|||||
| Pin 5 | Pin 4 | Pin 3 | Pin 2 | Pin 1 | |
| 1990-1991 | 5 YEL | 5 YEL/BLK | --- | .5 BLK/YEL | 5 YEL |
Clip wire from Pin A ( DK GRN/WHT) and wire from Pin E (YEL) and wire them together. Leave some excess sticking out of the wiring harness in case you ever want to revert back to using the relay again.
I would prefer to have used a large butt connector and shrink wrap, but I made do with what I had on hand. Just make sure the connection is secured firmly and covered safely.
Your car should start right up now.
