Hello,

Will a used engine wiring harness from 91 190e 2.3 work on 93 190e 2.3.?? Both are California cars. The CEL is on in my car (93 190e 2.3 4cyl) and my mechanic diagnosed the issue to be a bad wiring harness. Apparently there is open circuit on the AFM wire & Coolant temp sensor wire. Please advise.

Thanks
