Electrical issue
'95 coupe auto. While driving "SYS" will flash three times then go back to mpg readout. Owners manual states "may be a problem with your electrical system" It seems to drive fine. Recently changed OEM stereo to aftermarket using wiring harness from Crutchfield. The cruise control was not engaging last time I drove the car.
I was going to un hook stereo first, then check connections for cruse control. Any other areas to check when it warms up a bit.
Thanks

Did you install resistors on the stereo lighting circuit?
If not SYS will flash because system is looking for circuits that are not there with aftermarket setups

Thank youfor your quick response. No I didn't. Do I put it inline on the wire for lighting and what value resistor? When I bought the wire harness and antenna extension from Crutchfield nothing was mentioned about the resistor.

Looked through bulletin, noticed the it relatetes to '90 - '93 with electronic air which pertains to my '92. My '95 has manual air. The aftermarket radio has a circuit board no wires.
