Red blinking light on left side of dash by tachometer. what is it

This is most likely your "Valet" alarm disable switch. Use to disable your car alarm so you can keep your Alarm Fob and let a Valet, mechanic, friend etc. operate the car without the alarm being functional. If it is an after market alarm, consult the mfg's manual, if OEM contact dealer for operating instructions.

security light

Red goes to the ignition switch fuse for power in the fuse box green goes to the the negative side of the distributor white is for the tachs light so it will go to the dash light fuse in the fuse box and black is for the ground.

i believe that is your anti theft light

blue and black can be tied together and chasis grounded. green goes to the distributer side of the coil. white to the dash lites or light switch fuse. the red must go to a on switched 12 vdc or switched b+.

first check that the dash light dimmer knob is not turned to very dim (far left). It is located in the dash instrument cluster slightly left of center between the tachometer and speedometer near the bottom edge.

If that seems okay, check out the No. 13 fuse in the passenger's side under dash fuse box.

If the fuse is okay, you may have problem with the driver's multiplex control unit. This unit controls lighting for multiple other lights and switch indicating lights.

That is usually an indication of a blown bulb in the side that's blinking rapidly. Turn on the right side blinker and looking on the outside of the car, check all the bulbs that are supposed to blink and you will see on that is not blinking. Replace that bad bulb and the dash light will blink normally again.

Do you have an alarm system installed? These sound like the alarm indicator lights. They are supposed to deter theft and break ins.

the red light means power limited. the yellow ESP light is part of the traction control system.. if you were on slippery ground its a normal thing to happen if the tires spin

did you check for loose connections in the wiring harness, fuse box, or fuses?
